Add server — Counter-Strike 2

Enter the address players connect to. We query it over Valve A2S on the spot, and if the server answers it joins the Counter-Strike 2 listing immediately. Name, map, version and player counts are read from the server itself, so there is nothing else to fill in.

Before you add it

A server that is configured wrong is not rejected quietly — the form tells you which check failed. These are the ones that matter for Counter-Strike 2.

Valve A2S

How we query Counter-Strike 2. Default port 27015.

A2S_INFO

The query port must accept UDP from outside. Most hosts open it by default.

sv_setsteamaccount

Not needed for this check, but a server without it drops off Steam lists.

Query port

Equals the game port on almost every host. Fill the second field only if yours differs.

A public address

LAN and loopback addresses are refused: nobody else could join them.
