The error you are getting is WSAECONNREFUSED (you can find a lot of useful information googling just for 10061)

This means, there is no server on the machine/port you’re connecting to. You can try telnet to the machine and port, from the client machine, first.  Get telnet to work, and spits out the server’s “welcome” network packet, then client won’t  return 10061 either. Maybe you just need to open the firewall on that port.

PS. Dbeaver does not use MySQL client. It uses JDBC drivers.

Subject: [Maria-discuss] mysql 5.5 client vs mariadb 10 server

Hi,

I'm sorry for the question if it is clear that it isn't possible. 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...
