Home Assistant 2022.9.7
Supervisor 2022.10.0
Operating System 9.0
Everything worked fine until yesterday. I haven’t made any updates to Home Assistant or changed anything on my LAN.
Reinstalling the integration didn’t do anything - same Error.

Error setting up entry WolfOS for wolflink

As I can see from the Wolf SmartSet app, there is a connection to the Wolf cloud.
And I can’t find open issues for this error. Edit: Error setting up entry Wolf for wolflink · Issue #73317 · home-assistant/core · GitHub
Any ideas?
Update: Problem solved
Login Wolf Portal (Cloud) → Remove the heating system there → Add the heating system there again (a password with numbers, letters and lower and upper case is now required) → Reinstall the Wolf integration → Working again
