EDIT: solved by changing the Instance URL
According to this https://github.com/home-assistant/core/issues/73319 topic the problems with the spotify integration should be solved.
However for me it still fails.
I am running home assistant on Synology docker.
External url is using dockdns port 8443
I think I tried all possible options for the redirect url in the spotify developers settings everything fails.
Anyone faced the same and found the correct url ?
I use version Home Assistant 2022.8.1
