Problems with spectating

Ever since the login-twice issue (3 weeks ago for me), I've also had the problem with spectating other people/ my friends. I've noticed that the login thing might be fixed (yay), but the spectating issue still isn't.

1. Spectate friend
2. Screen goes black
3. After waiting awhile/ alt-tabbing, "It says unable to connect, a firewall might be blocking..." (something along those lines). Which definitely isn't a problem with my firewall.

I've tried this 10+ times, every time it fails. Other people seem to be having this issue as well. I believe this is an account restricted issue.
