As far as I can tell, everything is configured fine, and it is merely rejecting your login credentials, so it must be the email address/password somehow.
So... I guess double-check that the (full!) email address and password are valid and typo-free for logging into the web interface.
...
I know Gmail has their stupid "Insecure Apps" thing because they want you to use OAuth for no good reason, but that is Gmail specific so it shouldn't be a problem with GMX.
If the service was unavailable (GMX is not the most reliable service, sadly) then there should've been an entirely different error message.
