Ah ok. You would need to start dedicated server on client machine with client turned on too and make client join that machine… But it’s meaningless to start dedicated server on client machine, because you would run 2 instances of the game on single machine which is more resource intensive and 2nd on security aspect, dedicated server will still run on the client where he can alter data on it, so even if you can’t access those object on the client good enough hacker will deal with server that runs on there machine
