Networked Hp Bar

Ok so after the the luxury of developing and testing on host client I have come to realize some problems that occur on clients that aren't the host client. One of which is my hp bar.

Ok so I have a canvas attached above a player prefab with the hp bar and a script to make it face the camera. I have a Player class that is responsible for feeding the correct variables to the hp bar scripts. The player class in created on the NetworkManager after creating the player prefab that contains a NetworkBehaviour PlayerController. It creates player object, and runs PlayerContoller.Init(player) to set its player variable. The hp script pulls from there, playercontoller.player.health example.

I will show you my scripts, please if someone can help me figure out how to solve this networking error I would be highly appreciative. Here we go.
