Redirect Uri - spotify intégration my.home-assistant.io

Hello,

I have been using the Spotify integration for a long time. However, lately it no longer works, I wanted to reinstall it, but without success.

When I use the login link for Spotify is this. I don’t understand why it uses (https://my.home-assistant.io) when I registered my domain no.

> https://accounts.spotify.com/authorize?response_type=code&client_id=MY-CLIENT-ID&redirect_uri=https://my.home-assistant.io/redirect/oauth&state=eyJ0eXAiOiJKV2QiLCJ5bGciOiJIUzI1NiJ9.eyJmbG53X2lkIjoiZWIyMmZhZDI1MDUyMWNiNjJkZTZmNWJiOTE4ZmVjMmUiLCJyZWRpcmVjdF91cmkiOiJodHRwczovL215LmhvbWUtYXNzaXN0YW50LmlvL3JlZGlyZWN0L29hdXRoIn0.2pY5KxT1ZJuNBCv36vSBN2_C196XDfXZSW2KdNwlu0Q&scope=user-modify-playback-state,user-read-playback-state,user-read-private,playlist-read-private,playlist-read-collaborative,user-library-read,user-top-read,user-read-playback-position,user-read-recently-played,user-follow-read

So I have a white screen with (INVALID_CLIENT: Failed to get client).
I have tested the different solutions that have not been found on the net, without success.

I also use Nginx reverse proxy, can this cause problem?

Thank You for the helps
