Spotify cannot be added after upgrade to 2021.5.5

I upgraded Homeassistant to version 2021.5.5. But now Spotify does not work anymore. I tried to re-install the integration but I get a message: The server got itself in trouble when I get redirected from the autorisation page of Spotify.

Can somebody give me any suggestions?

I may be experiencing the same issue. I get the following error message:

Retrying setup: 400, message=‘Bad Request’, url=URL(‘’)
