Since installing el capitan public, I cannot sign in to my company jabber server in any app. I was using adium without any issues - now I can't sign in with adium, or messages, or anything else. I have to admit, I'm kind of stumped. Firewall is disabled. It starts signing in, and during authentication it just sort of hangs up and never finishes. Am I the only one, or have others seen this behavior as well?
