SSL/TLS debugging on MariaDB

[Andrew Wood]

Hi

Is there a way to get  MariaDB on Bookworm to log verbosely everything 
to do with connection attempts in order to try and debug why a client 
keeps getting error  2026 SSL connection error: protocol version mismatch?

There is currently nothing being logged on the server other than:

 [Warning] Aborted connection 332 to db: 'unconnected' user: 
'unauthenticated' host: '192.168.253.231' (This connection closed 
normally without authentication)

SHOW GLOBAL VARIABLES LIKE 'tls_version'; gives TLSv1.1,TLSv1.2,TLSv1.3 
and the client is based on a relatively recent version of libmysqlclient 
so Im struggling to understand what is going wrong without some more 
detailed logging. I cant find anything in the MariaDB manual.

Thanks

Andrew
