No I haven’t got it to work. Mine still can’t find sessions on the LAN, but can join by directly opening the private LAN IP address of the host device. So I added some UI stuff to fetch and display the IP address (for the host) and input an IP address to join (on the Client devices).
You can’t host, either? That sounds like a completely different problem to this one. Do you get an error when you attempt to host, or does it just not create a session? If it doesn’t create a session, how do you know it didn’t create and that others just can’t find or join?
Make sure you added OnlineSubsystem=NULL to your DefaultEngine.ini unless you also want to use steam in which case you put Steam in there. Also make sure when you Create, Find, and Join Sessions the Use LAN bool pin is set to TRUE if you want to do it on LAN.
