Hi,
I'm not even going to talk about the virtual network or Docker config here. Each of those introduce another level of complexity.
Many versions of MYSQL need additional configuration / security settings to allow a connection via TCP/IP from a different machine. A different machine is defined as a different IP address.
Also: Can you ping from one machine to the other?
Cheers,
Paul
