Well, you’re not alone. Some other people have reported the similar problems here.
They seem to think the problem is server side and has something to do with audio.
You can try disabling audio to see if that helps. Obviously, it would suck not to hear alarms, and it’s only a temporary solution, but it might get you up and running until CCP fixes the issue.
If you think your problem is unrelated to the audio one, you should probably mention it in the official feedback thread. It also wouldn’t hurt to file a bug report and/or a support ticket.
And, please come back and tell us how this issue was ultimately resolved. It may help someone else.
