HaruHostJoin by address
- Open the server in HaruHost and go to its Details tab.
- Copy the Server Address (address and port) and send it to your friends, with the password if you set one.
- In Core Keeper, your friends choose Join Game → Join with IP, enter the address and port, and join.
Joining from the same house
Many home routers can't reach their own public address, so when you host on your own address, the PC next to the server can't join with the address you send friends. The Details tab lists a separate Local Address for players on the same network; it works on Windows and for servers without the Tunnel.
Friends without port forwarding
With the Tunnel on, the Server Address goes through HaruHost's relay, so friends join without any router setup. See hosting without port forwarding.
Questions
Where do I find my Core Keeper server's address?
On the server's Details tab in HaruHost, in the app or the web panel. The Local Address there is for players on your own network, on Windows or without the Tunnel.
