Have you had the opportunity to familiarize yourself with ERR_SSL_VERSION_INTERFERENCE when using Google Chrome or Mozilla Firefox when visiting a website? So do not worry. This is a common mistake reported by many users. You can fix it very easily.

In this article, we will tell you what this error is, what are the causes and what are the different methods you can use to solve it. You can also read our article "Your connection is not private" which deals with a similar problem.


Found in Chrome or Mozilla, this error occurs primarily when the browser and Web server use different versions of Transport Layer Security (TLS). If your browser is up-to-date, it's usually the website that has not activated the latest TLS 1.3 protocols. Different antivirus and even browser data can explain this error. There are different ways to solve this problem and we will discuss this in the next section.

Fixed SSL ERR version interference on Chrome

Before you begin, make sure your browser has all the latest updates. If not, see if the browser update removes the error. Also make sure your date and time settings are up to date. If you still can not access the website, follow the methods described below.

Method 1: Disable third-party firewalls

Your antivirus may consider some websites to be a threat based on their SSL certificate. It is possible that this causes an error in your browser. Try to disable the firewall and see if the website is loading. We will list the steps to follow to disable the firewall in one of the most common antivirus software: Avast. If you use different software, do not worry, the steps are pretty much the same.


  1. Launch Avast Internet Security and select Protection.
  2. Under Protection, you can find a firewall. By disabling it, you will have the choice of four options. Select how long you want to keep the firewall disabled and confirm.
  3. Try reloading the website that was generating the ERR_SSL_VERSION_INTERFERENCE error to see if it is resolved.

Method 2: Disable TLS 1.3 on Your Browser

This method will most likely fix the ERR SSL VERSION INTERFERENCE error. Note, however, that TLS 1.3 provides important performance and security updates over previous iterations. With that in mind, if you are sure, follow these steps.

  1. Open a new tab in Chrome.
  2. Copy chrome: // flags and paste it on the address bar. Press Enter.
  3. In the search bar, type TLS1.3 and set the result to Disabled.
  4. That's all there is to it and you can now check if the website works.

Conflicts resulting from cookies and cached data can lead to Err SSL Version Interference error. This can be easily solved by deleting all navigation data. To do this on Chrome, follow these steps.

  1. Start Chrome and press Ctrl and H.
  2. This will open the History tab. Next to the history of your browser, you can find the option to clear the browsing history. Click on it.
  3. In the next dialog box, select the Advanced tab and check all boxes. Set the time range to Hourly and press the pending data, which will be blue.
  4. When done, check if the error persists when reloading the website.

Method 4: Use Chrome Cleaning

This is a tool provided with Google Chrome. It looks for all the malicious programs that can hide in your system and removes them. To use this tool, simply follow these steps.

  1. Launch Chrome and open its menu at the top right corner.
  2. In the menu, open the settings and scroll down the settings page.
  3. You will find the advanced options at the end. Click on it.
  4. Under the Reset and Clean heading, click the Clean Computer option.
  5. If Chrome finds something suspicious, it will uninstall it. Reload the website to see if it works.

Method 5: Disable Hardware Acceleration in Chrome

Hardware acceleration is a very useful feature that allows Chrome to increase its performance and speed of navigation. But sometimes, leaving it on can cause problems, including the ERR_SSL_VERSION_INTERFERENCE error. To solve this problem, simply follow these methods.

  1. Run Chrome, open the settings menu and go to advanced settings, as in Method 4.
  2. Under System Header, you can find the option for hardware acceleration. Turn off
  3. Reload the web page to see if the error still persists.

Method 6: Reset Chrome

If none of the above methods worked for you, it will only be left to reset Chrome to its default settings. Fortunately, Chrome allows you to do it quite easily. All you have to do is follow the steps below.

  1. Open advanced Chrome settings. You can refer to steps 1 and 2 of Method 4.
  2. Again, just like Method 4, under the Reset and Clean heading, you can find the option to reset the settings to their default values. You will be asked for confirmation. Confirm and you can start using Chrome with its default settings.
