Attempting connection with an totally invalid connection string hangs indefinitely.
Attempting connection with a partially invalid connection string results in a timeout.

It is quite common for users to get the connection string from the Atlas console (with placeholders for user/password,  paste it into Compass and immediately click connect without changing the placeholders.

Suggest we disable the connect button unless the connection string is valid?
