Exception: 502 Bad gateway

[brunofin]

I'm trying to transfer my playlists from Spotify to Google Play Music. Tried this today (27/06) with the latest version from pip on Fedora 23.

I've used this program before and it worked perfectly, fast and flawlessly, but now, on step 4 when it should transfer the selected playlists to PLay Music, the webpage hangs and the following error keeps being thrown in the Python console:

Ah nevermind, after trying 3 more times, it finally worked. Maybe the Spotify servers were down? Unlucky me.

I'll leave the issue open though, so you can decide whether you want to handle this error or not.

I got this issue as well and also on the third attempt it worked fine. For anyone else getting the error, simply refresh the page, reselect the tracks you want and keep submitting till it works

I added some retry logic, hopefully this fixes it.
