To solve the problem of ERR_SSL_VERSION_OR_CIPHER_MISMATCH error in Chrome, clear your browser cache, verify the system date/time, switch off old security measures, and update the Chrome. In case, it is your site, change your server setup and your SQL certificate to allow new versions of TLS and strong cipher suites.

This is a mistake that is typically caused by old settings of an SSL or a problem on the server-side and clearing of cache, disabling of QUIC, activating of TLS or determining the certificate of the site usually enables secure access.

To fix the ERR_SSL_VERSION_OR_CIPHER_MISMATCH error in Chrome, update your browser and OS, clear SSL state, disable outdated TLS settings, check system date and time, flush DNS, and ensure the website’s SSL certificate and server configuration are valid.

Update Chrome and your operating system, enable TLS 1.2/1.3, clear SSL state, disable outdated security software, and ensure the website supports modern SSL protocols. If it’s a site issue, contact the site owner.
