If you’re developing with Unreal Engine, you must implement a method to allow Multiplay to bind the IP address of your game server instance, unless your server binds to 0.0.0.0.
Unreal Engine has known issues with passing the correct IP address from cloud instances to the network address translation (NAT). You can circumvent these this problem by implementing a method to allow Clanforge to bind to the game server IP address. We’ll record the IP address on Clanforge, then pass it to the game server instance via a custom variable or command-line parameter at launch.
