Wolf SmartSet Binding - COMMUNICATION_ERROR Authorization failed

Dear Community,

can somebody.help me or does somebody has the same issue?

Since some time, my Wolf Smartest Binding cannot connect anymore.

I completely removed the Binding from “Things”, then I installed 4.1.2
After re-adding the Binding “WolfSmartSet Account”,

I still get the error message:

  • openhab/things/wolfsmartset:account:9893a90971/statuschanged
    ThingStatusInfoChangedEvent
    [{“status”:“UNINITIALIZED”,“statusDetail”:“NONE”},{“status”:“OFFLINE”,“statusDetail”:“COMMUNICATION_ERROR”,“description”:“Authorization failed”}]

I checked the credentials, but I still can login with the same credentials into
https://www.wolf-smartset.com

Is this maybe not working anymore, in general?
Or am I doing something wrong?
