Ubuntu :: Empathy - Network Error - Lucid?

I get error when I try to login my yahoo account. It seems okay with Gtalk, I havent checked the others because I use yahoo for most of time. It blows out network error no matter how i try: killall tempathy-butterfly (it's probably not running on my system, I've tried with killall telepathy-haze,salut which are running and having relative with telepathy ), edit host file, change the server name by adding cn before it. But it's still no go up to now.

My alternatives are meebo or wine and trillian, worked, but is there any chance for Empathy or Pidgin (it gives me error: connection refused)? It's just happened for 3-4 days recently, i dont know whether my network has configured right or not. Hope someone give me a hand which should embarrass me to continue living in linux bug world.
