While working with Skype, a message often appears stating that a connection cannot be established. Appearing in inopportune moment, the message breaks the connection, preventing you from ending the conversation. Getting Skype back to work is easy. You need to understand the causes of the problem and perform a sequence of actions.

Reasons for the error

After entering your login and password, this data is sent to the server for verification. After confirming the data, the server informs the program on the computer that the data is reliable and authentication has been completed. If a connection error occurs, this means that the program cannot synchronize with the server and does not allow the user to access the network.

Among the reasons for the lack of connection are the following:

1. The version is outdated and no longer relevant.
2. The program is blocked by the Windows Firewall.
3. The computer is not connected to the network.
4. The provider has blocked Skype.
5. The program server is not responding.
6. The program has crashed.

I will analyze cases in which a malfunction occurs in Skype.

Checking your Internet connection

The first thing to do if Skype is unable to establish a connection is to check your network connections. Launch any browser and try to access any website. If there is no Internet, we see a corresponding message.

Checking the program version

Microsoft regularly releases updates for its product. The company is interested in ensuring that users use only new versions of the product. Therefore, older versions are unstable and often crash. Information about the current version is available in the “Help” section. In the pop-up window, click About Skype.

In addition to the version, the manufacturer indicates the year the update was released. Versions released last year are considered out of date.

The update is made through the official website. Go to Skype.com and click “Download”.

Disabling the firewall

Another reason why Skype says “The connection could not be established” is Windows lock. Firewall is a standard protection that is present in all Windows versions. It blocks suspicious activity from the network. Firewall - useful application, but its work also affects stability useful programs and applications. In particular, it can cause problems with Skype. To check the impact of the firewall on the software, you need to temporarily disable it:

Disabling antivirus

The antivirus has a list of programs that it blocks or prohibits access to the Internet through them. Skype sometimes falls into their number. If this happens, add the program to the antivirus exclusion list, and network access will be restored.

Router settings

Crashes in Skype work are caused by improper operation of the router. To eliminate this possibility, do the following.

One of the most popular operating systems today mobile devices is "Android". It has a number of huge advantages over its competitors and is an almost undisputed leader. However, relatively recently, reports began to arrive about problems with one of the main services of Android devices, namely Google Play. When logging in, the application began to display an error: “A reliable connection cannot be established.” The system help provided by the suppliers does not help. Then how to solve the problem that has arisen?

Fast and easy

To begin with, we will present a method that will not require you to perform any complex or dangerous operations with the gadget. The simplest solution to the "Unable to establish a reliable connection" error is based on system settings. You just need to check system date and time in your Android device. They must coincide with the real ones within one minute. This is due to restrictions on the validity of program certificates. If the date is incorrect, the phone will consider that the validity period of the certificate has not yet arrived or has already passed.

Clean up

This method is suitable for those who do not have any important data saved on their device. Although, in fact, you can always transfer photos and videos to your computer and download applications again, especially if you have synchronized your data with your Google account. Then, even if you reinstall, all application data should be preserved. So, there are two ways to resolve the “Unable to establish a reliable connection to the server” error.

1. Reset your phone to factory settings. You can use special programs that application developers offer, or find instructions that are specific to your Android device model. After all, each manufacturer has its own tricks and protection mechanisms.
2. Add new account. As you understand, old data will not be copied to new versions of applications, but you can avoid problems with transferring other information that needs to be saved when complete cleaning phone. To add a new account, do the following:

• Download the AddAccount application via your computer or phone browser.
• Write the downloaded apk file to the initial directory on your phone's memory card.
• IN standard browser enter: content://com.android.htmlfileprovider/sdcard/add_account.apk.
• Follow the link.
• Launch the program. Enter your email on Google and click Add Account.
• When a message appears about wrong password enter it and continue. That's it, you have a new account.

In addition to drastic methods, there is also a less dangerous solution. “A reliable connection to the server could not be established” is an error that is related to the temporary and personal data of the application. That's why possible exits From a problematic situation, you can look in another area.

Freedom

Statistics show that sometimes problems with Google Play can be related to other applications. In particular, the Freedom program. She is responsible for purchases in the application we are considering. The problem where you can't establish a reliable connection to the server can occur if you downloaded and uninstalled Freedom without first forgetting to turn it off. As is clear from the above, to return everything back, download and install this utility. After that, enter it and stop it by clicking on the Stop button. Then you can safely delete it.

Internet

If the previous method did not help you, you should check your Internet connection settings. Problems like “Cannot establish a reliable connection to the server” may occur with some providers, but incorrectly. Before trying to solve the problem using this method, try opening Google Play by connecting to another Internet source. If you still need to return to the initial option, download the Set DNS application. Install DNS address 8.8.8.8. This should help in cases where Wi-Fi is used to connect to the Internet. In any case, first try to test your device on a different connection.

Another option for why a reliable connection to the server cannot be established is possible blocking server. In order to check this method, you will need superuser rights on your device. Open Explorer and find the file /system/ect/hosts. We need to open it with anyone text editor. By default, the file should only contain - 127.0.0.1 localhost. We delete any remaining data.

YouTube

The last method to solve the problem lies in additional programs. It is assumed that the user cannot log into Google Play due to incorrect addressing settings in the Google account.

A utility pre-installed on many Android devices for viewing videos from YouTube (or any other program that uses for registration) will help you cope with this problem. Google account). The bottom line is that you just need to launch the application and go through it to your GMail account.

other methods

And finally, it’s worth mentioning two more extreme measures. The first of them is “Hard Reset”. Full reset device settings. To do this, go to the application menu, select "Settings" - "Backup and reset". After that, in the last window, click "Reset". And delete everything. After which the device should return to its original state. You will have to download all the programs again and set up an account.

Flashing. Update the operating system or reflash the device. The second option is undesirable, since after it you may well be denied warranty service. It's best to just update the OS. Many manufacturers try to independently correct errors that occur to users.

That's probably all that we could tell you and advise you to do when the error “Cannot establish a reliable connection to the server” occurs. We hope our article helped you.

Skype failed to connect

Problems with connection in Skype are usually associated with outdated software or equipment, non-compliance with technical Skype requirements, viruses or bad Internet.

Skype can't connect

If you can’t log into Skype and it says “failed to connect”, most likely you have outdated version programs. Install a new one using official center downloads:

This is the surest way to solve the connection problem, however, it does not work in all cases.

Sometimes the connection error may be due to firewall ban use the application and it, of course, does not see the network and cannot establish a connection. In this case, check to see if Skype is on the list of prohibited programs and remove the ban if necessary.

If you access the Internet via proxy server, and Skype cannot automatically detect its settings, this may also be the reason why it cannot connect. In this case, go to "Settings" through "Tools" main horizontal menu, further in "Advanced settings" And "Compound", and provide the information you know:

If the data is known only to your admin, and he does not want to share it, alas, you will most likely continue to write “check your connection” until you can change the way you access the Internet.

If you've tried all the recommendations above and still don't know why you can't connect on Skype, try checking what you're typing to see if you're entering it incorrectly: this non-obvious solution might work!

Sometimes Skype does not connect and does not see the Internet due to viruses– check your device for viruses.

By the way, connection errors may be accompanied by both the message “could not connect to Skype” (or “cannot connect to Skype” if you have a non-Russian version) and the notification “Unfortunately, we could not connect to Skype.” True, in the latter case this may be due to the quality of communication.

Why is Skype offline?

Why is the call dropped? Sometimes in Skype status"writes" "Offline"- in this case you need to update or reinstall Internet Explorer . It just so happens that even if you don't use this browser, on devices running on Windows, Explorer is preinstalled program and affects the operation of some applications run by Microsoft. So you should just update it to latest version.

Internet connection problems

Why is the connection interrupted or lost? As a rule, Skype's Internet connection settings are loaded automatically and match the network settings of your device. How to set up a connection if you access the network through a proxy server? Proxy servers are detected automatically by default, but you can manually enter the required ones host And port(and data required for authorization if this is a proxy requirement):

If there is no connection or problems with it on your device, the program will also malfunction: you will be faced with the fact that constantly connection breaks, the call is interrupted or dropped, there are no beeps or there are none, and so on.

IN in this case questions “why the connection drops” or “why does Skype keep disconnecting” should be addressed not to the program, but to your equipment, telecom or Internet service provider: They are the ones who are responsible for why the Internet connection is poor. However, if you haven’t found a way to improve the connection on your computer or how to connect your phone to the Internet, Skype offers its own solution:

Since you can only establish a connection in this way from your Skype account, you can only use it if you have a positive balance. Therefore, this is not a solution for everyone.

Other connection problems

If Skype says "this user can only receive messages via chat", check next setting– it’s better to select the item here "receive calls from anyone":

If that doesn't work, try the other steps above.

If the program writes that "no active internet connection found", will help here Internet update Explorer, as well as deactivating the icon "work autonomously"(depending on versions, it may be in the “File” or “Tools” menu; in the latest version there is no such option).

If you get the error “add contact - check connection”, also check Explorer. Update it (browser).

BUT! It's best to update your device software and Skype version to the latest. They generally eliminate error messages, as well as the errors themselves.

And if you want to know how to communicate via Skype without the Internet, unfortunately, there is no way. To communicate without access to the Internet, use a regular mobile or landline connection.

If you're wondering why bad connection in Skype, then it is worth considering that if you, for example, use WiFi, and the access point is far from you, then the data transfer speed will be quite low. That is, the closer the communication device is to the access point, the higher the transmission speed. This may also be the reason why the video turns off or slows down during a conversation.

"Could not install Skype connection“This is a common problem among users. However, even if you saw such an inscription, the situation is not hopeless. In our article we will try to list everything possible reasons error appears.

If Skype writes that it was unable to establish a connection, this means that there is some kind of failure during authorization, there is no connection with the server and, accordingly, you cannot log into your account.

Why can't Skype connect?

Let's list the main reasons why Skype cannot establish a connection to the Internet.

1. The device you are using has an outdated version of the messenger. We recommend it, updated, beautiful and pumped up. The problem will probably resolve itself.
2. The program conflicts with an antivirus or firewall, and they block it (do not allow it through). You need to disable them for a while and try to log in again.
3. Bad Internet, or something happened with its settings.
4. Skype does not connect to the Internet, although the Internet is working? Perhaps the error is within the application itself (for example, a critical failure occurred).
5. Problems on the official server of the developer, where user data is received.
6. Malware, viruses or malfunctioning operating system(you will have to reinstall).
7. If you use Skype in an office or enterprise (from a work computer), then keep in mind that full-time IT specialists, at the request of management and within the framework of corporate policy, can limit employee access to applications that have little to do with the work process. In this case, nothing can be done.

If you updated the messenger, but Skype still says “the connection could not be established,” then it’s time to start setting up the settings.

What to do if Skype fails to connect

1. Update the program

Try installing Last update programs. If you updated the messenger, but Skype still says “the connection could not be established,” then it’s time to start setting up the settings.

2. Check your firewall settings

Skype is not working, the “Connection failed” message is still looming, your nerves are on edge. Idea! Let's check the firewall settings.

These programs are not much different from each other, so the algorithm for optimizing their parameters for interaction with Skype is usually as follows:

1. Turn off the messenger.
2. Open the firewall. If you can't find it, go to the notification area (bottom right corner of the screen) and look for the icon there.
3. This software monitors all applications installed on the device. There is a list of them there. Find the messenger in it.
4. Configure the permissions for it so that the program can connect to the Internet.
5. Save the changes, then restart Skype and try to log in.

More detailed instructions on the use of firewalls you will find them on websites software developers. Also, do not forget to update the settings of the similar built-in Windows Defender (see Control Panel - System and Security).

We talk about what to do, if at all, in our other article.

3. We diagnose the proxy server parameters

Still having problems with Skype and still unable to establish a connection? Let's diagnose the proxy server parameters (what if your connection to the Internet is made this way).

Important! If you don’t know anything about the characteristics of your proxy server or feel unsure when manipulating the software, then please do not change anything.

For desperate and risky users, we suggest the following procedure:

4. Error within the application

Skype may be unable to establish a connection due to some kind of glitch occurring within the program. In this case it's worth a try reinstall the program.

5. Problems on the official server

If the problems are on the developer’s server side, then nothing can be done on your own. All that remains is to wait.

6. Viruses

If your PC is infected with viruses, seek help from an antivirus. If it detects malware on your computer, you need to clean the system using special utilities, or completely reinstall the operating system.

7. Access restrictions

If access is limited by the company you work for, then there is nothing you can do about it. You will have to wait until the end of the working day.

What else can you do if Skype fails to connect?

Change password

It seems like you've already tried everything, but Skype still hasn't managed to establish a connection - what should you do?

There is another way - you can change the password.

Resetting your browser settings

Well, perhaps the last hack for today is reset Internet settings Explorer (if this is your default browser). This method also often helps in solving similar problems with authorization.

1. Close all programs, folders and files, launch the browser.
2. Hold down “Alt” on your keyboard.
3. In the menu bar, find “Tools” - “Browser Options”.
4. In the “Advanced” tab, click “Reset”.
5. Check the box next to “Delete” Personal settings" and press reset again. You can restart your computer.

Internet messenger Skype is the most popular program for users to communicate online. With its help you can make voice and audio calls, exchange text messages and files, organize online conferences and even call landline and mobile phones. The main advantages of this program are that it is free, simple and high level security.

But even such a reliable and high-quality tool as Skype cannot guarantee that at some point its operation will not fail. Problems with the messenger are not such a common occurrence, but they still occur. One of the most common is network connection failure. The error that appears is that when logging into Skype, it says that the connection could not be established.

The causes of the problem may be different, related to both global network settings, and with the program itself, which happens much more often. At the same time, Skype usually does not connect to the Internet, although there is Internet, and other programs that use it connect perfectly to it. Let's figure out why Skype sometimes writes “The connection could not be established,” and what can and should be done to restore it normal work. We will move from simple to complex.

Temporary unavailability of the service

It's unlikely, but it could be that your ISP, network administrator (on corporate computers), or even your own firewall is blocking access to Skype domains. Then it is not surprising that the user cannot log into Skype. To exclude this possibility, go through Internet Explorer (!) to the page www.skaip.su/proverit-dostup-k-skaypu and click the "Check" button. The status of all servers should be “Connection successfully established”.

If a connection could not be established for at least one of the servers, this will indicate one of the three reasons listed above.

If everything is in order with the firewall (how to check it below) and Skype still cannot establish a connection, contact your system administrator or contact your Internet service provider's support service. We also recommend checking the functionality of the Skype servers themselves on the page www.skaip.su/status-serverov-skayp. The servers must have the “Working” status, otherwise you need to wait until the technicians themselves fix the problems.

Outdated version of Skype

By default, Skype is updated automatically and this is important, since the messenger works correctly on local computer directly depends on server services.

If you are using an older version, at one point the program will not be able to connect to the remote host, and you will receive the error described above. It is not difficult to determine the version you are using, you just need to select it in the main menu Help - About Skype.

You can also check availability there. new version applications.

If your messenger is out of date, go to the official website of the developer and download current version. Close the broken program and run the web installer. The latest version will be downloaded to the PC and installed immediately, while old version will be deleted. If installation problems occur, it is recommended to completely uninstall Skype, including the user directory %userprofile%/AppData/Roaming/Skype, then perform cleaning CCleaner registry or other similar instrument.

Note: Skype folder, more precisely the main.db file in the directory AppData/Username, contains correspondence history. If you don't want to lose it, create it just in case backup copy, but in general, for starters, try limiting yourself to deleting the shared.lck and shared.xml files.

Outdated version of Internet Explorer

Since Skype desktop uses MSIE components, the connection error may be due to Internet browser Explorer. It is noted that in some cases Skype does not work and says “check your Internet connection” in Windows with the sixth and seventh versions of IE. For a successful connection, at least the eighth version of the standard browser must be installed on the system. Please update your built-in browser to version 8 or the latest version available for your OS.

Resetting IE settings won't hurt either. To do this, open its properties (via the classic control panel or by pressing Alt and selecting Tools – Browser Options).

Next, switch to the “Advanced” tab in the window that opens and click “Reset.” Before resetting, we recommend checking whether the SSL 2.0, SSL 3.0, TLS 1.1, TLS 1.2, TLS 1.0 checkboxes are checked in the same tab. If not, install the birds, restart the browser and check the operation of Skype.

Blocking by firewall or antivirus

If you are using a built-in or third-party firewall, try disabling it for a while.

Restoring the connection will indicate that Skype is blocked by a firewall. Disabling this protection completely for the sake of Skype alone is not the best best idea, but you can create a separate rule for the messenger that allows incoming and outgoing connections. You should also check whether Skype is accessible in the settings for allowing interactions between applications and components.

At the same time, it’s worth checking your antivirus’s “loyalty” to Skype and, if necessary, adding the application to its white list.

Action of viruses and modification of the HOSTS file

The cause of the problem may be a banal virus that has overwritten the contents HOSTS file. Scan the system thoroughly antivirus program, check if there is specified file"left" servers. The HOSTS file is located at C:/Windows/System32/drivers/etc, you can open the file itself with any text editor.

By default, the contents of this file should look like the one shown in the screenshot.

If there are any addresses listed below, delete them.

Ports and proxies

If you use IP address spoofing programs on your PC, temporarily disable them or create (if the appropriate option is available) an exception. Users who have previously configured a messenger connection through a proxy should check the validity of the IP address and port. Skype will not work and the connection will not be established if the port is blocked or has low throughput. We remind you that the proxy settings are changed on the “Connection” tab in additional settings applications.

For correct operation messenger, ports 80, 443, 3478-3481 UPD and 49152-65535 UPD+TCP must be open on the computer. Check them in any online port scanner, for example, 2ip.ru/check-port and, if any of these ports are closed, open it by creating a separate firewall rule for it or a group.

Interestingly, some users reported that the connection was restored when they unchecked the boxes that allowed the use of ports 80, 443 and the upnp protocol. Try this option too.

Router settings

Incorrect router configuration is another reason why the “Connection could not be established” message appears in Skype. The ports may be blocked in the network device. To enter the router settings, go to the browser at 192.168.0.1 or 192.168.1.1, the default login and password are admin/admin. In most routers, the subsection you need is called “ Virtual servers", but there may be another name. For example, in D-Link it is “Firewall”.

Virtual servers or VPS are a special service that simulates the work of a real physical server. On a single computer, it provides complete and independent control over local network and can be used as part of setting various restrictions, for example, parental controls. In theory, the “Virtual Servers” subsection should be empty. If there are already settings there, try to find out who made them and for what purpose. Perhaps you yourself ordered this service from your provider and forgot about it.

Pay attention to the “External port (end)” parameter. Let's say it's 49650.

So, this value must be specified in additional Skype settings on the “Connection” tab, namely “Use port [number] for incoming connections.”

If the “Virtual Servers” subsection is empty, you can create your own VPS to resolve the Skype connection error. In this case, we take the values ​​for the start and end external ports from the range 3478-3481 UPD and 49152-65535 UPD+TCP. Select the appropriate protocol.

Perhaps this will be interesting

Above, we looked at the main causes of problems and learned what to do if Skype writes “The connection could not be established.” For the most part, the tips offered were related to desktop and portable versions messenger, but this program also has a web version, which can be used in IE, Chrome and Firefox. It is available at web.skype.com. In general, the web version duplicates the functions of the desktop version, but for it to work correctly you need to install a plug-in. You will be prompted to install it when making your first incoming or outgoing call. If you have Windows 8.1 or 10, don't forget about universal version messenger.
