My Question or Issue

Hello all.

I have this Blazor Server app that is playing (in a browser) using the Spotify Web Player. I can get authorized and I get a Token and a RefreshToken and I can successfully use this to play a track. The refreshToken is saved for later.

The problems start when an hour has passed and the token is not valid anymore. I have however supplied a new refreshed token to the routine that plays a track.

I call https://accounts.spotify.com/api/token with the saved RefreshToken and get successfully back a Token. This is used in the Play routine that play a track and this is successfull. But when the hour is up I get errors.

The original token starts with BQAN8OXE .... but the refreshed one gets

BQDPgMvMQ (I doubt that this is significiant) 

Does anybody have a clue of what goes wrong here or perhaps example where refresh token is in use.

Kind regards

Martin
