# How do I fix the SSL "unknown error number" error when connecting to MySQL?

You may get a `ERROR 2026 (HY000): SSL connection error: unknown error number` error when you try to connect to MySQL or MariaDB with an outdated client that does not support TLSv1.2 or TLSv1.3.

To fix this error, upgrade your client to a version that supports TLSv1.2 or TLSv1.3. MySQL also supports [many options for customizing connections](https://dev.mysql.com/doc/refman/8.0/en/mysql-command-options.html).

For more details on MySQL versions and their supported TLS versions, see the [MySQL Encrypted Connection TLS Protocols and Ciphers docs](https://dev.mysql.com/doc/refman/8.3/en/encrypted-connection-protocols-ciphers.html).
