That additional connection is clearly wrong.... the mysql server would never start with "ftp." and I'm not sure about the other settings.
Update the additional connection page to reflect the correct connection information for your remote database and it should start working properly.
Your other connection isn't using this wrong information, so that explains why it works differently.
Do you have a separate remote and testing server and database? If not, then removing the additional connection should work.
Did this help? Tips are appreciated...
