Hipchat Firewall Fail

Update 3-9-2011: Turns out Peer Guardian was somehow blocking port 5222 which is required by the HipChat application. I’ve no idea why any of the other remote apps that I run daily (GotoMeeting, Logmein, Join.Me, SocialCast, Yammer, Trillian, etc) did not have any issues.
Congratulations to HipChat on being the first chat application that I can remember that has ever reported firewall issues on my computer. Can you imagine rolling this out to 10 to 20 (or more) people and having to debug everyone’s firewall issues?
I can’t.Uninstalled. Test drive over.
