Client Travel to Server fails with seamless Travel enabled

I have successfully implemented the SessionInterface into my project. But when I switch to using “AGameMode::bUseSeamlessTravel = true”, I can no longer connect a client to a listen server.

When I am joining a Session, I simply call IOnlineSession::JoinSession. When the associated delegate fires, I use IOnlineSession::GetResolvedConnectString to get the URL to call APlayerController::ClientTravel and immediately connect to the server. I am also logging out that URL, and noticed that it’s different when I am using SeamlessTravel: 192.168.178.36:0 with SeamlessTravel enabled and 192.168.178.36:7777 with SeamlessTravel disabled.

This is all done using my PC, my Android phone and OnlineSubsystem Null.

Any help for getting Seamless Travel to work is very much appreciated :slight_smile:

Did you manage to work out what the problem was? I’m having the exact same issue now
