I Havn't been able to get the web player to load for about a month now. When the page loads it loads everything but the album art and clicking any song results in "Oooops, something went wrong with the playback"
I've looked in the developers console in both Chrome 64.0.3282.24 and Firefox 57.0.1 and the only thing that stands out is guc-spclient.spotify.com/track-playback/v1/devices has an HTTP 429 status code when initiated by open.spotify.com/browse/featured but an HTTP 200 status when initiated by raven.js.
Both browsers have had the cookies removed and cache purged and still do the same.
Firefox also has api.spotify.com/v1/me/notifications/user?connection_id= giving an HTTP 400 status code, but Chrome does not, so i think its inconsequential.
Any help is appreciated!
