I had sudden issues a few weeks ago with this library, where it would refuse to connect to Spotify for access token renewal or other stuff. After a lot of messing around it seems it's just the SSL fingerprint(s) being outdated. These are the current fingerprints for .spotify.com and .scdn.co. I didn't try to connect to the spotify image CDN, but since it has a different fingerprint now than the one specified in the header file I suppose it might have changed recently as well.
