Dbeaver uses mysql client binaries for some of the operations but most of them are done using the jdbc drivers by the version you choose. You should choose mariadb and not mysql.

I'm trying connect from a mysql 5.5.56 client against a mariadb 10 server and I'm having the next error: ERROR 2003 (HY000): Can't connect to MySQL server on 'server' (10061) Subnet source is allowed in mariadb server and grant is given for 'root'@'source_server', it is allowed both IP and hostname. So not sure if it is config problem or compatibility problem. Someone knows please? Thanks beforehand. P.D.: I can connect using dbeaver from my computer client using mysql binaries (but not sure what mysql client version uses dbeaver). Cheers...
