My Question or Issue

API calls returns me 500 all of a sudden
Im running a local host web project .net. Yesterday it was working fine, and all of a sudden, i'm getting 500 responses :(.

I'm trying to get tracks for a an album :
https://api.spotify.com/v1/albums/4PLQ6R5CJrjXJJeW8uaup2/tracks
My token is in the header as  (new AuthenticationHeaderValue("Bearer", token.AccessToken);)
It works to get my saved tracks. Was working yesterday, and now, i get 500 with content : {"error": {"status": 500, "message": "Unknown error" } }

What's happening ? 😞
