I've made 3 attempts to setup Meltano tap-mysql, on different environments, with no success. I use the UI to set the credentials, but it can never reach the database. Any other users with the same issue? Is there a preferred way to setup tap-mysql?

I have it working in a number of places but I don't use the UI. Have you tried configuring it/running from the command line?

ok, i'll give that a go instead.
