Hi.So i was just playing on a map about 5 mins ago when it gives me the popular error "server connection timed out".then the server list doesn't ... list any servers.i cant see any server in the list.please if someone knows how to fix this respond.

that means that server has shutdown means the admin closed the server then you can't connect to it nor you can see it in serverlist. if you don't see any servers in the list try deleting caches.xml and launching game if that also doesn't work try to re-install 4D1 IW4M : iw4m/InstallIW4M.exe
