"Error: Resource not found" and "Error: Could not determine type of stream" on all songs

It seems to have gotten worse. Now, Pithos only reports the following:

The song list stays blank. I try to change stations and get:

INFO - pithos:station_changed:541 - Selecting station 524154548952858343; total = 26
INFO - pandora:get_playlist:247 - pandora: Get Playlist

    self.audioUrl = d['additionalAudioUrl'][self.pandora.audio_format]

I'm no longer seeing the original error.

This new error looks like bug #1009343. Try changing the audio format in the settings window.

Experiencing "Resource not found"

I retract my previous statement.

System Settings -> Network -> Network Proxy -> Method "None"

Fixed. I apologize for taking up any time.
