If you encounter the error "ERROR 2026 (HY000): SSL connection error: unknown error number", it often indicates that your client does not support modern TLS versions. Stackhero's MySQL instances are configured to support only up-to-date TLS protocols and ciphers for enhanced security.

This error might occur if your client tries to use TLS v1.1, which is outdated and unsupported by modern MySQL and MariaDB versions. To address this issue, you may need to upgrade your MySQL client to a version that supports the latest TLS protocols.
