Forums Connection Issues Unable to connect (permission denied)

I have the exact same problem..

* Unable to connect to server (Permission Denied)

No one can tell me what it means. It's a new problem, I've been able to connect in the past. I've tried disabling my firewall temporarily without luck. I've tried a fresh install of mIRC which didn't work either. My other computer using the same connection through wifi can connect fine. Please help.
