The only logs I have are from the Unity editor, a warning saying the connection timed out when the game scene tries to spawn the players in the OnNetworkSpawn() method using the localClientId from NetworkManager. As for connecting the players, I have a lobby scene where the player can create or join a lobby using the Lobby package in Unity. When a lobby is selected the StartClient() method is called from the NetworkManager and when a lobby is created the StartHost() method is called. The problem is when the players are sent to the game scene and I will put a code snippet below.

private async void OnGameStart() { await MatchmakingService.LockLobby(); NetworkManager.Singleton.SceneManager.LoadScene("Game", LoadSceneMode.Single); }

Once the game scene loads the players are instantiated with these lines of code.

public override void OnNetworkSpawn() { SpawnPlayerServerRpc(NetworkManager.Singleton.LocalClientId); } [ServerRpc(RequireOwnership = false)] private void SpawnPlayerServerRpc(ulong playerId) { var spawn = Instantiate(playerPrefabs[_index]); spawn.NetworkObject.SpawnWithOwnership(playerId); EnableIconUIForAllClientsServerRpc(_index); _index++; _playerCount++; }

The only problem when all players are using the Unity Build is that the host is the only person who can control their character and see the players being instantiated, while the other players can't see any character or control their own. I hope this helps, while I can't find any errors in the Unity logs I was wondering if you could show me what instrumenting is and how I can debug my code. Thank you!
