Buddy Constantly Listed As "Not Authorized"

[Joseph Beck]

Hello,

My girlfriend and I are using pidgin via XMPP accounts, both hers and 
mine are through the same XMPP domain. We have reauthorized several 
times but every time I log in she is listed as "Not Authorized" on my 
buddy list. Today while we were talking I was apparently deauthorized 
mid-chat from her buddy list which was the first time it's happened to 
her. She had been doing nothing but typing a response to me in her chat 
window. We've tried reauthorization option and just readding each other 
to the buddy list. Many times. Is this a bug or is there some way to fix 
this on our end?

If it matters, I am using Ubuntu 13.04 and she is using Windows 8. 
Pidgin had been working perfectly fine before when I was using my 
Google(XMPP) account instead of a normal XMPP account.
