Multiplayer not working after following UE4 tutorial

I was following along the Multiplayer Blueprint Tutorial that is on the UE4 youtube and got to part 11 and tried testing the multiplayer with my friend and it said no sessions were found, LAN or Internet. I tried it on another computer in my house and no sessions were found either. I went through the video again to make sure I had everything. The multiplayer connects when i have 2 players in the editor but when i package and try 2 instances of the game running on this computer it doesn’t work. If you need screenshots of any blueprints just ask.
