Unable to connect to subsonic install behind nginx proxy/redirect

I am unable to successfully query a subsonic installation that is behind a nginx proxy/redirect over HTTPS. My subsonic install is very similar to what is outlined here in this guide, so that I'm able to use sane SSL/HTTPS settings and not the config that comes with subsonic. This setup is totally accessible via web browser and other subsonic applications (e.g. D-Sub on android).

If I remove subsonic from behind the proxy/redirect, I can connect to it from py-sonic.

Here's the relevant code in my application where it fails (I have tried other methods besides getArtists as well, they also fail with the same error)

          subConn = subsonicConn()                                                 
          subConn.connect(configOpts.get('Server','url'),                          
             configOpts.get('Server','username'),                                 
             configOpts.get('Server','password'),                                 
             configOpts.get('Server','port'))                                     

         self.artists = subConn.getArtists()

I do not want to supply my url, user, or pass for obvious reasons.. but if you'd like to reproduce this and test a possible solution please let me know and I'll create a guest account for you to test on my subsonic server.
