Problem
No DHL labels can be created. One of the following error messages occurs:
Anmeldung fehlgeschlagen
login failed
Der Nutzer des Webservice konnte nicht authentifiziert werden
Invalid GKP username and/or password
Nutzername oder Passwort nicht korrekt
Cause
All the above error messages indicate the same problem: the DHL server has rejected the login credentials (username / password).
Solution
The login must be configured correctly, or the password might have to be renewed.
Also make sure that two-factor-authentication (2FA) is not enabled for the API user.
Please follow these instructions to configure the DHL login data.
