Crash when behind a proxy server

Hi! Thank you for adding proxy support! Though I still getting 407 Auth Required exception after successful Spotify API authorization.

Here is stack trace:

Thanks, I'll get it fixed when I can.

update note: the issue is due to authentication not using proxy settings but the api client itself is
