CFTools Cloud is one of the consumers of your game servers metadata interface. The type of interface used and underlying protocol depends on the game server title you are operating.

These interface operate from a "query port" which must be available to all players, Steam and our crawlers. Without this server metadata, CFTools Cloud and more important your players are not able to properly find your server in server browsers.

You need to configure this query port in your server configuration, and it must only be once. Multiple servers may not use the same port, and the port can not be used for anything else while in use. You may need to create firewall rules in your system and network level firewall appropriate to your configuration and environment.

Our crawlers operate from a dedicated IPv4/IPv6 (if supported) for each individual title. You may find the used address below:

We may change these ip addresses at our sole discretion.
