problem with docker connection

Hello, Recently it was no longer possible to connect to MySQL Docker (with port 3307) with HeidiSQL :-( All connections are aborted - see screenshot.

Connection to such dockers

Did you already try the other libraries like the error dialog suggests?

If that doesn't help, I recommend to have a look at the (Windows) Firewall, which is sometimes automatically blocking things.

Apart from that I have no experience with Docker. But I guess it's working similar like a virtual machine, so you need to check the network configuration.

If that all doesn't help, try to connect per command line, using mysql.exe. If that connects well, we probably have a HeidiSQL issue.
