I’m seeing the same problem for UE 5.5. When using ServerTravel the client then reoslves the port to 0, when using gameplaystatics the client successfully resolves the port as 7777. Although if I just hardcode the correct IP when doing the connect from the client after having used servertravel for the server it still doesn’t work, so it’s not just about the client resolving the correct address, it’s something FUBAR with the server travel itself.
