Resolution Note:
Remove the portion of the player script that has the server spawn the player object when the player object is spawned as this is done automatically for you. The reason it is complaining about the object being spawned twice is that it is being spawned again on the server side when the player prefab is automatically spawned in the Player script.
If you want to spawn a custom network prefab per player, review over the Changing the player Prefab section in the NGO documentation.
