Bug Failed to find any loaded scene named "XXXX"!

I am trying to connect 2 players together using the relay, the first player joins fine but player 2 gets an error "Failed to find any loaded scene named Game!" I've tried using the relay with NGO as well as UTP but got the same error both times. I am loading the scene by LoadSceneMode.Single

Code (CSharp):

1.  
2.  
3. if (IsServer && !string.IsNullOrEmpty(m_SceneName))
4. {
5.             var status = NetworkManager.SceneManager.LoadScene(m_SceneName, LoadSceneMode.Single);
6.             if (status != SceneEventProgressStatus.Started)
7.             {
8.                 Debug.LogWarning($"Failed to load {m_SceneName} " +
9.                       $"with a {nameof(SceneEventProgressStatus)}: {status}");
10.             }    
11.    
12. }

 

Is the "Game" scene in the Player Build settings scene list? If not, it needs to be.

 

It is in the build settings!
