The plugin stopped working.

[tuFFo126]

Mopidy has stopped playing tracks from Spotify (using the mopidy-spotify plugin); it was working fine about two weeks ago. I installed the new gst-plugin-spotify_0.15.0-alpha.1+spotify-logging.3aab047 (previously I had 0.15.0-1.4), but it still doesn't work. It fails to authorize the audio stream.

This is what it looks like when trying to play a song from Spotify.

Hi! It looks like Spotify changed something. You can follow the discussion in this issue: #437
