How to Fix the ERR SSL VERSION OR CIPHER MISMATCH Error

Some users have encountered the ‘ERR_SSL_VERSION_OR_CIPHER_MISMATCH’ error when browsing certain websites. If you are experiencing this issue, it is not due to any action on your part as an end user.

This error can appear in any web browser, including Chrome, Firefox, and Edge. It indicates that the website you’re trying to access uses an SSL certificate that your browser rejects.

The error can also occur if the SSL certificate stored on your PC is corrupted or if there are misconfigurations in your system’s TSL/SSL settings. Below are several effective methods to help resolve the ERR_SSL_VERSION_OR_CIPHER_MISMATCH error, particularly in Google Chrome.

1. Access the Website Using HTTP

The first step is to try accessing the website using HTTP instead of HTTPS. Simply replace “https://” with “http://” in the website’s URL.

For example, instead of accessing https://ugamasontech.com, try http://ugamasontech.com. If the error persists when using HTTP, the issue lies with the website itself, and you will need to wait for the site owner to resolve it.

2. Clear the SSL Certificate Cache

Windows allows users to clear the SSL certificate cache, which can often resolve this error. Follow these steps:

1. Open the Windows search bar and type Internet Options.
2. Select Internet Options from the list and go to the Content tab.
3. Click on Clear SSL state.

3. Modify Chrome’s Flag Settings

If the issue persists, you may need to change Chrome’s flag settings. Follow these steps to adjust the SSL version support:

1. Open Google Chrome and type chrome://flags in the URL bar.
2. Find the Minimum SSLv3 version Support option and set it to SSLv3.
3. Restart Chrome to apply the changes, and the error should be resolved.

4. Disable the QUIC Protocol in Chrome

QUIC Protocol is an experimental protocol by Google that can sometimes lead to SSL errors. Disabling it may resolve the issue. Here’s how:

1. Open Google Chrome and go to chrome://flags/.
2. Search for QUIC on the Experiments page.
3. Set Experimental QUIC Protocol to Disabled.
4. Restart Chrome.

5. Clean Up the Windows Registry

A cluttered or corrupted Windows registry can also trigger the ‘ERR_SSL_VERSION_OR_CIPHER_MISMATCH’ error. Using a tool like CCleaner can help clear up junk registry entries:

1. Download and install CCleaner.
2. Open the software and go to the Registry tab.
3. Click Scan for Issues and wait for the scan to complete.
4. Click Fix Selected Issues to clean up the problematic entries.

By following these methods, you should be able to resolve the ERR_SSL_VERSION_OR_CIPHER_MISMATCH error on your browser. Learn More
