I have a public cod2 server(patch 1.0) on windows server(vps)
when i run server its ok but after 1-2 hour server just get "SV_AuthorizeIpPacket: challenge not found" error and any player cant connect to server.

I tried these:
1-block cod2authorize.activision.com in windows host file
2-fresh install of cod2
3-run server without any custom mod
4-disable firewall
5-disable anti ddos

but i have this problem yet.

I installed anti ddos and problem solved!
