Hi, thanks for this awesome API!
I got a problem and I've tried to debug it without any luck.
I have a javascript that calls a function after any 5-10 sec randomly. That function gets data from Spotify API through my PHP file that uses your library.
It works well for hundred times without any issue, then I got this error message very randomly.

I use client credentials authentication, there is some problem with that part, as I can see.

Thx, Peter

The error message:

Hi!
It looks like Spotify is returning you a 502 Bad Gateway server error. I'd file an issue over at their repo and wrap your call to Session->requestCredentialsToken() in a try/catch where you retry the request and prevents it from crashing completely.

Closing this since I'm pretty sure it's an issue on Spotify's end. Just give me a shout if you want it reopened!
