"Why doesn't my multiplayer work? I have two separate systems and two accounts on LAN, and I want to test Steam multiplayer.

Join and Create

In player to create a session and find and join one

I am using two computers on the same LAN with two different Steam accounts. When I try to click ‘Join Game’, it loads for a moment but then kicks me back to the main menu or starting level. I know that something is crashing, but I don’t know why or where to look. I need help to fix this multiplayer issue.

  1. What class are you executing this code in?
  2. Get Player Controller (Player Index) should not be used for multiplayer.

None of these should be used in Multiplayer.
