Veteran ARK server host here: I've just spun up a test Atlas server and even though the process is running and listening on the correct ports (this is Linux) and the server is receiving packets to the listening port, the server is reporting offline when polled by steam view > servers list (prompted manually).   Well, I think it's running. The stdout from the application is: ATLAS@Games:~$ bash servertest.sh Using binned. 4.5.1-0+UE4 7038 3077 409 10
