I use to get this problem...here's a fix I used.
.Make your computer static ip (lan ip).
.Go to your router+modem settings or both if they are separate (if they are make your router also static ip from your modem settings).
.enable port range forwarding - 28960 for that static ip.
.enable UPnP Forwarding - 28960 and choose UDP for that static ip.
And thats it...but if players are suddenly joining and suddenly leaves. Join a game or ask a friend to join your party before entering the host commands.
