- Get TCPVIEW from sysinternals ( http://technet.microsoft.com/en-us/s.../bb897437.aspx ) and use this to see if something is actually running on port 5222 already, if so, evaluate what it is and decide if you need to remove it.
- If not, restart PC, Router, Modem and then see.
- It could just be a temporary problem with your ISP, or the quakelive servers.
- ZoneAllarm commonly causes this problem, open port 5222 in ZoneAllarm or try a different product instead.
- check you can resolve xmpp.quakelive.com by attempting to ping it ( ping xmpp.quakelive.com in a command prompt) ask others to confirm the IP is the same. If not have you altreed your "hosts" file? remove any quakelive entries from it.
QL also uses udp 27000-27999 for game traffic which you may need to open on some firewalls if you are having problems.
The only other ports needs are standard http and https ports for the browser ( 80, 443) which you won't need to open,
