Your browser will examine the SSL certificate of every website you try to link to. In order to verify that the website you’re visiting is real and has utilised the right protocol to protect your connection, you can use this tool.

The Handshake protocol is a term for this type of communication. Web servers and computers use TLS to encrypt and decrypt data exchanged between them.

TLS handshake, both the browser and the web server do not support a common SSL protocol and cypher suite during the TLS handshake. A notice stating ERR_SSL_VERSION_OR_CIPHER_MISMATCH appears in the browser window when this occurs.


This website refuses to provide a network connection for a variety of reasons. Reasons for this include:

  • Certificate mismatches can occur when a domain’s SSL certificate is incorrectly given to the wrong website domain name.
  • Web browsers that are too old – The latest TLS version may not be compatible with older operating systems and web browsers.
  • It is possible that Google’s QUIC protocol, a replacement for popular security solutions, will result in the error.
  • Website security updates may have been missed by a web browser’s cache.
  • False alarms from antivirus software – if the antivirus programme malfunctions, the

Fixing the Error Message “ERROR: SSL Version/Cipher Mismatch”

The ERR_SSL_VERSION_OR_CIPHER_MISMATCH problem is straightforward to fix, despite the fact that it appears sophisticated and daunting to new users.

ERR SSL VERSION OR CIPHER MISMATCH can be fixed in six different ways.

1. Clearing the SSL 

If you are unable to establish a reliable connection using Chrome, you should also try removing the SSL state. Perform the following procedures to check the SSL status on Windows browsers:

4. Verify the SSL Certificate

First and foremost, you should examine the SSL certificate if the client or server doesn’t support the same SSL protocol version and cypher suite.

Chrome allows you to view certificates and undertake in-depth investigation and evaluation of free online tools. The one provided by Server SSL Labs is the best option.

5. Removing Temporary Internet Files and Cookies

After experiencing an online error, it is critical to delete your browser’s cache and cookies, as these are typically the source of all kinds of issues.
