Connection closes right after handshake (setting up LobbyBeacons)

I’m trying to setup up LobbyBeacons and it seems like i maybe need to do more to make it work… the output log from the host looks like this:

And the client side log is like this:

I have managed to get the HostBeacon and Client beacon to connect, but it seems like this only is a low level handshake.

*Extra info : I’m using SteamOnlineSubsystem to connect the players

Anyone have any ideas on where to go from here?
