How to fix ssl connection error. SSL connection error, what should I do? So to clear the SSL cache

If the site has SSL installed, the page opens securely https protocol:

The green color in the address bar signals to users: personal data (bank card number, email account, password) will not be stolen here.

It’s annoying when a green traffic light turns red at the wrong time. It’s doubly annoying if, instead of a secure connection, you suddenly see on the website: SSL protocol error. Why this happened and how to fix and remove the SSL connection error, read below:

Check in advance

Make sure you don't confuse the SSL connection error with other problems. If your website stops opening in your browser, first check:

Is a redirect from http to https configured for /;

What domain is the SSL certificate installed on? An SSL certificate is registered for a specific domain. That is, if the certificate is installed on a domain and you accessed through the address shop., then an SSL error will be shown.

If you have a free SSL certificate installed, it only applies to the domain itself and the “www” subdomain: and www.. It does not work for other subdomains. If you need an SSL certificate on a subdomain, order a separate certificate for the subdomain:

Why does the SSL error occur?

• The system clock or calendar settings have gone wrong;
• your antivirus program scans data transmitted via the HTTPS protocol and may block some traffic;
• the settings of the browser itself have changed;
• a malicious script is triggered.

SSL protocol error, what to do?

Below are 4 drop-down blocks. Each contains an answer to the question of how to correct the error depending on the cause.

System clock and calendar settings

If the time settings on the computer are lost, the browser will warn:

In Google Chrome

In Mozilla Firefox

The solution is simple: set the correct date. To prevent the error from recurring, enable synchronization with a time server on the Internet (system settings Dates and times).

Antivirus program settings

If everything is fine with the clock and the SSL error is still there, check your antivirus program settings. Most likely it includes "check https protocol". Check if it is enabled, the program will not accept or the certificate is protected Let's Encrypt. Try disabling the function and visiting the site again.

If the SSL error persists, disable your antivirus program and open the site. Did this solve the problem? Changing the utility will help.

If this does not help, do not forget to enable your antivirus program and look for the solution below.

Browser settings

1. Open the site in another browser;
2. Check if you are using the latest version of your browser. If not, update it to the latest and open the site again;
3. This is probably a browser glitch. In this case, restart your browser and try to access the site again;
4. If the problem persists, disable web antivirus components in the Extensions.

A radical way is to reset the settings to the original ones. Use it as a last resort.

You can also change your browser to Internet Explorer until the problem is resolved. There is no SSL error in this browser.

Sometimes an SSL error indicates a real threat: your browser is protecting you from online scammers. It is likely that your browser opens a clone site to which you are redirected.

If you suspect hostile interference, scan your computer with an antivirus program and remove any existing viruses.

If the problem remains after the listed options, contact a specialist who will diagnose the specific case, identify what the ssl connection error means and fix it.

As you know, any application or program can fail one day - nothing is perfect in the world. So in the Google Chrome browser you can expect an SSL connection error. What does it mean and how to deal with it?

An SSL connection error occurs when opening a website, and such a website can be any resource, including both popular and not so popular ones. The error literally means the following: “Unable to connect to the server. The problem could be due to a server or client authentication certificate that you don't have."

This is what the error looks like in the browser:

Please note that it can occur not only in, but also in a number of other browsers that are based on Chromium: New Opera, Comodo Dragon, etc.

Problem and solution

I would like to immediately note that the reasons why this error occurs in the browser may not be related to each other. Therefore, the solution for each case will be individual. So I'll talk about a few possible solutions.

• The first step is to update your browser. Yes, the same Chrome is automatically updated, but in some cases the update can be disabled by the user. In addition, a glitch in the application itself cannot be ruled out. Therefore, click on the settings button, select “Help/About browser” and see if the current version of the browser is installed.

• Let's move on. Pay attention to the antivirus system. The fact is that it can block the SSL protocol as potentially dangerous, so it simply blocks it. In this case, you can try disabling the antivirus screens for a while and check whether the site opens in this case. In addition, in the settings of the antivirus program itself, you need to create an exception for this type of protocol.

• If you are using Windows XP SP2, you must upgrade to SP3. This solution was found on one of the forums and, according to user responses, it turned out to be very effective.

• Theoretically, the problem could be hidden in installed plugins in the browser itself. Go to settings, select “Extensions” and disable all extensions available there. If after this you were able to access the site, then the problem is in the extension and you just have to find which one is blocking the connection (disable extensions one at a time and you will find the culprit).

• Check your proxy settings. Go to your browser settings, find the “Network” subsection and click on the “Change proxy server settings” button. If a proxy server is specified in the network settings, it is possible that this is the problem. Select "Automatic detection of parameters" and go to the site.

• Alternatively, the problem may be with the site itself. But until the site owner sorts it out, you are unlikely to be able to access the site itself.

You can tell us about your solutions to the problem using comments.

The error “err ssl protocol error” is quite common in Chrome and Yandex Browser. It may appear when you try to log into any Internet site.

What is this error

The SSL protocol allows you to make the connection between your PC and the website secure. He encrypts data connections.

Chrome, Yandex and Explorer have certain certificates for SSL (SSL) in their functionality. If the specified certificates malfunction in the browser, configuration problems arise, then the secure connection to the site is disrupted and the system displays an SSL connection error.

There are several ways to help fix the error.

Viruses

Windows can be disrupted by viruses. Accordingly, it is enough check the system one of the antiviruses. It is recommended to use Kaspersky and Dr.Web.

date and time

One possible cause of an SSL error could be an incorrect time and date. The server considers this a danger and blocks access. Just open the BIOS settings and set exact values, corresponding to a country or a specific region. Now we reboot the device, first saving the changes made.

You can also change the time in Windows - the result will be the same.

OS update

Sometimes an error may appear when outdated operating system. To correct the situation, just perform the update manually.

Antivirus problem

Quite often, antivirus programs consider the connection dangerous and can block it themselves. To do this, go to your antivirus settings and disable SSL verification andHTTPS.

Making changes to the firewall list

In some cases, the error “err ssl protocol error” may appear when working with Google services, search engines or the browser itself. In this case, you need to make changes to your personal Security Settings. You need to add the application to the list of allowed nodes.

Browser replacement

In some cases, it may turn out that the main tools to correct the situation do not work. All that remains is change browser. You can use Opera, Firefox, or any others.

QUIC

A new protocol that facilitates fast connection to the network. You can disable it in the Chrome configuration.

After opening the browser, enter the command in the address bar: “ chrome://flags/#enable-quic" You need to enter without quotes. The system itself will display: “ Quic Experimental Protocol". Click on the link and press the button: disable. After this, just restart Chrome.

Using the HTTPS protocol

This protocol is used for secure network login. It can be used to log in when an error is thrown.

In order for the site to open, all you need is a standard HTTP address add letter S to make it HTTPS. Often, such manipulations help fix the “err ssl protocol error” error.

Changing security settings

Note that in Internet Explorer the system operates in automatic mode. The settings are in effect by default.

In the control panel, open " Network and Internet". After this, you need to click: “ Internet Options". Next we go to Privacy and move the slider to middle position.

Most resources use SSL v2.0 or 3.0. Some browsers do not work with these configurations. You can change these settings accordingly. To do this you need to do the following:

Checking hosts

This tool is used to set site redirects and create routes manually. The file is located at: C:\Windows\System32\drivers\etc. Open it using notepad with administrator rights. Completely delete the contents and save.

Disabling plugins and extensions

To disable all extensions for Chrome, just press 3 buttons, which are located on the right side of the browser line. Now open " Additional settings". Now open the extensions. All plugins and extensions that are currently in use will open in the window. Opposite them there is a button that can either enable or disable use. In addition, you can immediately remove unnecessary extensions and plugins.

One of the problems that a user may encounter when surfing the Internet through the Opera browser is an SSL connection error. SSL is a cryptographic protocol that is used to verify the certificates of web resources when accessing them. Let's find out what could be causing the SSL error in the Opera browser, and what methods can be used to solve this problem.

First of all, the cause of such an error may actually be an expired certificate on the side of the web resource, or its absence. In this case, it's not even an error, but the browser providing real information. The modern Opera browser in this case displays the following message: “This site cannot provide a secure connection. The site sent an invalid response."

In this case, nothing can be done, since the fault is entirely on the site’s side.

It should be noted that such episodes are isolated in nature, and if you get a similar error when you try to access other sites, then you need to look for the source of the cause elsewhere.

Invalid system time

One of the most common causes of SSL connection errors is incorrectly set time in the system. The browser checks the validity period of the site's certificate against the system time. Naturally, if it is set incorrectly, then even a valid certificate will be rejected by Opera as expired, which will cause the above error. Therefore, if an SSL error occurs, be sure to check the date set on the system in the system tray in the lower right corner of the computer monitor. If the date differs from the real one, then it should be changed to the correct one.

Left-click on the clock, and then click on the inscription “Change date and time settings.”

It is best to synchronize the date and time with a server on the Internet. Therefore, go to the “Internet Time” tab.

Then, click on the “Change settings...” button.

But, if the gap between the date set in the system and the real one is very large, then it will not be possible to synchronize data in this way. You will have to set the date manually.

To do this, go back to the “Date and Time” tab and click on the “Change Date and Time” button.

A calendar opens in front of us, where, by clicking on the arrows, we can navigate through the months and select the desired date. After the date is selected, click on the “OK” button.

This way, the date changes will take effect and the user will be able to get rid of the SSL connection error.

Blocking by antivirus

One of the reasons for an SSL connection error may be blocking by an antivirus or firewall. To check this, disable the antivirus program that is installed on your computer.

If the error repeats, then look for a different reason. If it disappears, then you should either change your antivirus or change its settings so that the error no longer occurs. But this is an individual question for each antivirus program.

Viruses

Also, the presence of malware on the system can cause an SSL connection error. Scan your computer for viruses. It is advisable to do this from another uninfected device, or at least from a flash drive.

As you can see, the reasons for an SSL connection error can be completely different. This can be caused either by a real expired certificate, which the user cannot influence, or by incorrect settings of the operating system and installed programs.

One of the most common problems on Android devices comes in the form of a browser notification that says, “Your connection is not secure.” This may raise doubts. This message pops up even on the latest devices with the latest updates and the current OS. This is not a big problem, but it still begs the question: “How to fix SSL connection errors on Android devices?”

Let's start with SSL/TLS certificates

A little about SSL. An SSL certificate, as you probably know, is designed to authenticate the authenticity of a website. The certificate authority that issues the certificate guarantees to the user on the other end of your connection that all communications between your browser and the web server are encrypted. This is essential because without SSL encryption, everything you do on a web page is in the public domain and may be intercepted or processed by a third party. However, with an SSL certificate, this communication is encrypted and can only be decrypted by the site itself. Visiting a site without a secure connection can end in disastrous consequences for you! To fully understand everything, you will need one more important information. SSL is currently only a colloquial term for the protocol. SSL stands for Secure Socket Layer, it was the original protocol for encryption, but TLS or Transport Layer Security replaced it some time ago. They both do pretty much the same thing, but at this point true SSL has been phased out (Android no longer supports SSL 3.0 - its latest version) and we're really talking about TLS certificates.

How to fix SSL connection errors on Android devices

When you receive an SSL certificate error message on your Android smartphone, you can fix the problem in several ways. If one of them doesn't work, try the next one. Ultimately, the problem will be solved.

1) Correct the date and time in your smartphone

This is a simple reason that can be resolved on Android. Just make sure the date and time are correct. To do this, go to Settings and select Date and Time. From there, simply activate the "automatically detect date and time" option.

2) Clear the cache in the browser (Chrome, Opera, Edge, etc.).

If fixing the date and time doesn't work, you should clear your browser history. This is another simple way. Let's take Chrome for example. Start by opening your browser and then click on Menu. Go to Privacy and select Settings. Then select "Clear browsing data." Check all the checkboxes on the screen and then click Clear.

3) Changing Wi-Fi connection

Try changing the Wi-Fi connection on your device if clearing data and resetting your time and date didn't work. You may be using a public Wi-Fi connection, which is known to be insecure. Find a private Wi-Fi connection and check if the error is fixed on Android.

4) Temporarily disable the antivirus

If you have an antivirus or other security application installed on your Android device, try disabling it temporarily and then turning it back on. Sometimes these applications can interfere with your browser, thus causing your SSL connection to fail.

5) Reset all settings on your Android device

This is a last resort option, but if all the other suggestions above fail to resolve the SSL certificate issue, you may need to format your device. The first step in this case is to back up your phone so that you don't lose everything you've saved on it. After that, select Settings and then Backup & Reset. Then click on Factory Reset.

We hope this guide showed you how to fix SSL connection errors on your Android devices.
