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
[S_API FAIL] SteamAPI_Init() failed; SteamAPI_IsSteamRunning() failed.
Setting breakpad minidump AppID = 834910
It's definitely listening and using a bunch of memory:
alexicon@Games:/home/ATLAS/ATLAS/ShooterGame/Saved/Logs$ sudo netstat -nlp | grep Shoot

Edit:
After some additional troubleshooting I found the following from the ShooterGame logs:
alexicon@Games:/home/ATLAS/ATLAS/ShooterGame/Saved/Logs$ sudo tail -f ShooterGame.log

I can see from the below post that this all looks okay, it's just that the server never starts:
In this admin's case, the server took over 400 seconds to load. So I've left it for over 1200 and no dice.
