Client not spawning and possessing (UE4 Multiplayer)

I’m trying to get a multiplayer game working. I followed this tutorial: UE4 / Unreal Engine 4 Multiplayer - #02 Player Spawning System - YouTube
I got the player spawning and possessing on the server side, but on the client window he wont posses the 2nd character. Can anyone please help me or point me in the right direction.

My GameMode_BP with 2 functions (GetPlayerStartPoints & SpawnPlayers) and my 2 players (Server & Client).

Function: Get all player spawn points.

Function: Get all players and spawn a character then posses.
