Check these first
- In Join Game → Unofficial, turn on Show Player Servers.
- Search for the exact Server Name from the Base Config card, and clear other filters such as map or password.
- Check that the server shows as online in HaruHost. A new map can take several minutes on its first start.
- Check Allowed Platforms on the Launch Arguments card. A server limited to Steam doesn't show for Xbox or PlayStation players.
If it still doesn't show
Players on PC can join by address meanwhile, by typing open and the Server Address in the console.
If joining by address doesn't work either, the server can't be reached from the internet yet. Turn on the Tunnel, or see port forwarding.
With the Tunnel
The list shows the Tunnel's public address, so the entry players click is one they can reach.
Questions
Does my ARK server show in the list when I use the Tunnel?
Yes. It shows with the Tunnel's public address, so friends find and join it as any other unofficial server.
