What the ERR_SSL_VERSION_OR_CIPHER_MISMATCH 
error means
• Website security has grown in importance as more and more 
firms conduct their operations online. Visitors to websites often 
see the ERR_SSL_VERSION_OR_CIPHER_MISMATCH problem, 
which is one of the most prevalent security faults. This error 
message often indicates a problem with a website's SSL/TLS 
settings.
• When a website's SSL/TLS certificate is set incorrectly, the 
ERR_SSL_VERSION_OR_CIPHER_MISMATCH error often appears. A 
user's browser tries to create a secure connection with a website's 
server when they try to access one that employs SSL or TLS 
encryption. The connection will fail, and the user will get the 
ERR_SSL_VERSION_OR_CIPHER_MISMATCH error message if there is 
a mismatch between the SSL/TLS version or cipher that the browser 
is using and the one that the server is using.
How To Fix The ERR_SSL_VERSION_OR_CIPHER_MISMATCH 
Error
Verify your SSL/TLS settings:
Make sure your SSL/TLS certificate is set up properly and that it is valid by checking it. You may check your 
certificate's validity and its installation of it using an online SSL checker tool.
Update your SSL/TLS certificate:
You must update your SSL/TLS certificate if it is out-of-date or has expired. Request a new certificate by 
getting in touch with your SSL/TLS certificate provider.
