Replication master: Server version: 10.5.21-MariaDB-0+deb11u1-log Debian 11 Replication slave: Server version: 10.5.21-MariaDB-0+deb11u1 Debian 11 When `require_secure_transport = on` is enabled on the master, I get: "error reconnecting to master 'user@domain.com:3306' - retry-time: 10 maximum-retries: 86400 message: Access denied for user 'user'@'domain.com' (using password: YES)." If I turn `require_secure_transport` off, replication works. So the error in the log *looks* like an authentication failure message, but it's clearly a TLS issue. journalctl -fu mariadb.service just shows the same: "Access denied for user 'user'@'domain' (using password: YES)" How can I get verbose messages about what is happening with TLS (why is it being rejected)?
