I am building a web application using the Spotify Web API. The calls are pretty straight forward and I don't understand if it is me doing something wrong, or if there is something wrong with the Spotify service.
I implemented the lookup call (works fine) and then add track IDs to my database when a button is clicked next to one of the results. I then do an ajax call to display that track in the "Play Button" iframe. Instead of showing my playlist now, I very often get a 502 Bad Gateway error. (This error also appears on the Spotify website where the example is supposed to be shown.)
Is this something I cause? My browser / system causes?
Thanks a lot in advance!
