Deutsche Post – Connection Failed
-
Hello,
For some reason I can’t get this plugin working. When I enter all required credentials and hit TEST CONNECTION button, I get the follow error:
– Connection Failed: Client authentication failed (e.g. unknown client, no client authentication included, or unsupported authentication method). The authorization server MAY return an HTTP 401 (Unauthorized) status code to indicate which HTTP authentication schemes are supported. Make sure to save the settings before testing the connection.
Would really appreciate your help with this!
Thanks
