“Err_ssl_version_or_cipher_mismatch” Error – An Expert Guide

Introducing our focus for today – the infamous “err_ssl_version_or_cipher_mismatch”. This is a troublesome yet not entirely insurmountable problem faced by online browsers around the globe. As an industry professional, I’ll be presenting to you my expert insights on how to conquer this daunting beast. So, grab your digital gear, and let’s dive in!


Understanding “err_ssl_version_or_cipher_mismatch

Good browsers, those that stand out in their digital territory, perform a vital ritual before connecting you to any website – the TLS handshake. This digital meet-and-greet validates the SSL certificate of the website, ensuring the communication is secure. However, the absence of a valid SSL certificate might suggest unsafe communication.

But what happens if the TLS handshake fails? You might presume it’d still let you onto an unsafe website, but that’s not quite it. Instead, you are faced with the dreaded “err_ssl_version_or_cipher_mismatch” error, a common sight in any browser. But don’t fret! With the right tools and techniques, you can navigate around this obstacle and reconnect with your favorite content.

“err_ssl_version_or_cipher_mismatch” in Chrome

The “err_ssl_version_or_cipher_mismatch” error often pops up when Chrome users try to visit a website. This typically signals an issue with the site’s SSL certificate, a digital stamp of approval asserting the website’s safety.

When an SSL certificate ages or becomes outdated, it may trigger the “err_ssl_version_or_cipher_mismatch” error. This doesn’t always happen but is frequent on sites requiring personal data, such as online banking or credit card information. So, how do we go about fixing this?

Overcoming the Err_Ssl_Version_or_Cipher_Mismatch Error in Chrome

Getting slapped with an err_ssl_version_or_cipher_mismatch error in Chrome can be frustrating, but don’t fret! Here’s a straightforward guide to maneuver through:

Time needed: 2 minutes

  1. Rally with the TLS:

    Hop into Chrome and put “chrome://flags” into the address bar. Find the TLS search field, select “TLS 1.3 support”, and enable it.

  2. Toggle the TLS versions:

    If your Chrome version is fresh, but the site’s SSL certificate isn’t, you can dial down to an older TLS version. Search for the “Enforce deprecation of legacy TLS versions” option and set it to “Disable”

Optimizing Your Internet Settings

For the Windows users among us, here’s a quick path to potential resolution:

  • Search for “Internet Options”, navigate to the “Advanced” tab, find the “Use TLS” checkboxes, and activate them all, from “TLS 1.0” through “TLS 1.3”.
  • Check the boxes for “SSL 3.0” and “SSL 2.0”.
  • Apply, Accept, and Reboot: Hit “Apply”, then “Ok”.
  • Restart Chrome for the new settings to take effect.

QUIC, Away with You!

Sometimes, Chrome’s QUIC protocol can stir up trouble. Here’s how to gently nudge it aside:

  • Go to “chrome://flags” in your Chrome browser.
  • Type “QUIC” in the search bar.
  • Find the “Experimental QUIC Protocol”.
  • Select “Disable”.

Keeping Your Firewall and Antivirus in Check

Even a misaligned antivirus setting can lead to the err_ssl_version_or_cipher_mismatch error. Here’s how to address that:

  • If your antivirus configuration seems suspect, try disabling it.
  • If available, turn off the automatic SSL scanning feature.

Clear the Cobwebs from Chrome’s Cache

Sometimes old data in your cache can cause trouble. Here’s how to give it a good sweep:

  • Head over to “Settings”, then “Privacy and security”.
  • Choose the “Clear browsing data” option
  • Check all the boxes in the popup window.
  • When all else fails, starting from scratch could be the way to Uninstall your current version of Chrome and download a fresh one.

Bypassing Err_Ssl_Version_or_Cipher_Mismatch in Edge

Similar to Chrome, Edge can also encounter this pesky error. Here’s how to tackle it:

  • Firstly, navigate to “Privacy & services” in “Settings”.
  • Select “Clear browsing data”. Then, restart Edge and try reconnecting.
  • Finally, enable all TLS and SSL protocols from the “Advanced” tab in the “Internet Options”.

Cleaning up SSL Certificate Cache

Last but not least, purging your SSL certificate cache might just do the trick:

  • Delete local cache: Type “C:\Windows\System32\inetcpl.cpl” in Windows.
  • Run dialog box.
  • Hit enter.
