How to implement multiplayer with top down template?

Hi, and thanks in advance for any suggestions. I’m attempting a multiplayer rts type, with two players matched up on a battlefield. I have some basic controls and UI, which work fine with single player…but not when I add another player. It seems that when two players join the game, both player controllers try to possess the same camera pawn, and getting ‘accessed none’ errors from the camera controls. The camera pawn will not be visible in the game, and is only relevant to the player possessing it. Do I still need to control the camera pawn through the server or is there something else I’m missing?

I have been working on something similar. I am not very experienced with Unreal though. I am about to sit down and look at your blueprints properly to see if they can help me with what I am stuck on. I will post anything I figure out on here.

My blueprints so far can be seen here:
