I encountered the same problem with the following stacktrace:

My solution was to terminate other java processes in my machine.

Answer 2

This can be caused by many things, I was wrong with this because of the mysql docker version. I changed the version from 8.0 to 5.7, it worked.

I suggest you check hostname, port, user, password and versions again.
