How to enable crossplay on a Valheim server

Add -crossplay to the server's launch options, so players on any platform can join, with no port forwarding needed.

-crossplay

Runs the server on the crossplay backend (PlayFab) so players on any platform can join, with no port forwarding needed.

-crossplay

Examples

-crossplay

Lets players on every platform join.

What it does

Without it, the server uses the Steam backend and only Steam players can see and join it. With it, traffic goes through a relay, and players connect by public IP and port, join code or the server list. Connecting by local or loopback IP does not work in crossplay mode.

Good to know

Add it to the server start line in start_server.sh (Linux) or start_headless_server.bat (Windows); it applies on the next server start.
Takes no value; include the flag to turn it on.

Run it on your server

Launch options go on the server's start line. Admin commands are typed in the in-game console (F5) by a player on the admin list. New to this? Start a Valheim server first.
