ERR_SSL_VERSION_OR_CIPHER_MISMATCH error happens if a website uses an invalid or outdated SSL/TLS certificate. This prevents the browser from validating the website’s SSL certificate to establish a secure connection.
Here are six ways to fix ERR_SSL_VERSION_OR_CIPHER_MISMATCH:
📌 Check SSL/TLS Certificate
Use Qualys SSL Labs to validate your SSL/TLS certificate and identify potential errors.
📌 Disable the QUIC Protocol (Google Chrome)
QUIC is a web traffic protocol that can sometimes trigger the ERR_SSL_VERSION_OR_CIPHER_MISMATCH error. Disabling it can fix the issue.
📌 Clear Web Cache (Google Chrome)
Deleting your browser cookies and cache can help remove old configuration data that might be causing the error.
📌 Clear SSL State (Windows)
Clearing SSL state on your operating system eliminates the need to remove each certificate on every page load.
📌 Enable TLS 1.3 Support (Google Chrome and Windows)
Make sure your web browser and operating system support the current TLS version.
📌 Briefly Disable Antivirus
Temporarily turn off your antivirus’ SSL/TLS scanning feature to check if that was causing the issue.
