Hi there.

I’m following this tutorial and I made menus and widget like what is in the tut. I cant confirm that the blueprints works in one system running two instances.
Now I want to test my game over LAN with a PC and a laptop connected directly with a LAN cable. So I copied my project in two system and run both. But when I host a game in one system the other one can’t find the session.
My systems can ping each other in windows command line but I don’t think that two game instances can see each other. Is there any way to check if two UE4 editors can connect together?

Also I added “[OnlineSubsystem] DefaultPlatformService=Null” to the defaultEngine.ini

Thanks in advance

Nevermind. I find out its from windows connection and not from UE4 side. Windows sucks on networking.

Ping is not importent here, the network multicast packets need to work in order for server discovery in LAN to work.

Note that you can direclly connect clinet to server via commend line arguments:
