If you’re an everyday internet user, chances are you’ll have to deal with one or the other browsing errors at some point.

One of the most common and frustrating errors that internet users encounter is the “ERR_SSL_OBSOLETE_VERSION” error message.

When you see this message on a website, it means that your web browser is unable to establish a secure connection with the website you’re trying to access.

Modern secure browsers are only compatible with the most recent versions of SSL/TLS protocols,  which offer superior security and encryption than their predecessors.

If a website uses out-of-date SSL/TLS protocols, it can pose a security risk. Hence, the browser returns the “ERR_SSL_OBSOLETE_VERSION” error message.

In this article, we’ll explain what this error means, what causes it, and most importantly, how to fix it.

Frequently Asked Questions

What Does the err_ssl_obsolete_version Mean?

SSL (Secure Sockets Layer) and TLS (Transport Layer Security) are encryption protocols that ensure secure communication between a web browser and a web server.

The ERR_SSL_OBSOLETE_VERSION means that your web browser is unable to establish a secure connection with the website you’re trying to access because it is using an outdated version of the SSL/TLS protocol.

What Causes the err_ssl_obsolete_version Error?

The number one reason you are seeing the ERR_SSL_OBSOLETE_VERSION is outdated SSL/TLS protocols. But that’s not the case all the time.

Compatibility issues between a web browser and a website’s SSL/TLS protocol can also result in the ERR_SSL_OBSOLETE_VERSION error. There are some other causes and solutions we’ll look at in this guide.

Fix #1: Disable SSL 3.0 and TLS 1.0/1.1

In 2019, Google Chrome and some other major browsers announced that they would be deprecating support for TLS 1.0 and TLS 1.1.

This was an effort to safeguard users from insecure websites and improve the browsers’ overall performance. However, Some websites still use these protocols to date. Hence, the ERR_SSL_OBSOLETE_VERSION error.

Therefore, in most events of this error, the first thing to suspect is the obsolete SSL and TLS. These are outdated versions of the SSL/TLS protocols that are vulnerable to attacks.

If you are keen on visiting a website that’s throwing up this error, you need to disable SSL 3.0 and TLS 1.0/1.1. You can do this via the native TLS stack on your computer. Here are the steps involved;

Click on the Search bar on your computer toolbar, type Control Panel into the Search box, and select the Best match result.


The Control Panel window will appear, Click on Network and Internet to proceed.


On the next screen, select Internet Options.


Next, the Internet Properties window will pop up. Switch to the Advanced tab and scroll down to the security settings to uncheck the box next to SSL 3.0, TLS 1.0, and TLS 1.1.


Click the OK button to save your changes. And that’s all. You’ve successfully disabled SSL 3.0 and TLS 1.0/1.1.

Restart your browser and visit the website again to see if the ERR_SSL_OBSOLETE_VERSION has been resolved. If not, proceed to fix #2.

Fix #2: Disable QUIC Protocol

The QUIC (Quick UDP Internet Connections) protocol was developed by Google to enhance website loading times and better network latency.

This ERR SSL OBSOLETE VERSION issue may show up on websites that are not compatible with the QUIC protocol.

To fix this issue, you need to disable the QUIC protocol in your web browser’s settings. Follow these steps to do it.

Open a new tab in your browser, type in chrome://flags/  in the address bar, and hit enter.


Next scroll down the page to locate Experimental QUIC protocol or simply type quic in the Search bar.


Once you find it, set click the dropdown next to it and select Disabled from the options.

After that, restart your browser and try to access the website again. If the ERR_SSL_OBSOLETE_VERSION still persists, continue with the next fix.

Fix #3: Clear Browser Cache and Cookies

Corrupt browser data, cache, and cookies can also be the cause of the ERR_SSL_OBSOLETE_VERSION error. In this case, clearing your browser data can help fix the error.

By clearing your browser cache and cookies, you’re essentially resetting your browser’s memory which helps take care of any compatibility issues that may be causing the error.

Here’s how to clear your browser cache and cookies;

Done! Your browser data has been erased successfully. Now, try accessing the site again to check if the ERR_SSL_OBSOLETE_VERSION error is no longer there.

Fix #4: Update Device Date and Time

SSL/TLS certificates are time-sensitive and have a specific validity period. If the date and time on your device are incorrect, it can cause SSL/TLS connections to fail. Hence, the ERR_SSL_OBSOLETE_VERSION error.

To resolve this issue, you have to correct your device’s date and time. Let’s See.

Right-click on the time or clock icon on your computer taskbar and select Adjust date and time settings.


The time settings page will open. Next, toggle on the Set time automatically radio button.


If the button is already turned on, try turning it off and then back on again. This will automatically update your device’s date and time.

Once done, close and reopen your browser. Now visit the website to check if there’s no more  ERR_SSL_OBSOLETE_VERSION error.

Fix #5: Disable Antivirus SSL Scanning

Antivirus software often includes SSL scanning features that can interfere with SSL/TLS connections, causing the ERR_SSL_OBSOLETE_VERSION error to appear.

Disabling SSL scanning in your antivirus software can help fix this issue.

Use the steps below to disable SSL scanning in your antivirus software. We’ll use the popular Avast antivirus for this tutorial.

Open Avast Antivirus on your computer and click on the menu (hamburger) icon at the top.


Select Settings from the resulting menu.


Next, switch to the Protection tab and select Core shields from the options.


In the Core shield settings, scroll to the Configure shield settings section, and switch to the Web Shield tab. Uncheck the box next to Enable HTTPS scanning.


And that’s all. HTTPS scanning is now disabled. To enable it again, follow the same steps.

Now launch your browser and check if the website is accessible. If not, try the other fixes below.
