Calling NetworkManager.ServerChangeScene() Destroys Player

When using NetworkManager.ServerChangeScene() to switch from stage 1 to stage 2, the player gets destroyed. There are no errors and the scene does change successfully.

What could the issue be?

Here is my code:

 [ServerCallback]
 public void LoadOnline (string sceneName) {
 
     NetworkManager.singleton.ServerChangeScene (sceneName);
 
 }
