Redirect Uri - spotify intégration


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 ( when I registered my domain no.


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
