Guys I have a question: the node “create session” (https://docs.unrealengine.com/…/Blue…/UserGuide/OnlineNodes/) does only create a lan session or a local session ? I’ve tried to use it to let my friend join into a server I’ve been able to create from that node but i got a problem: if I use another pc connected to the same wifi ,of the host, it find the server and I’m able to join the game but, if the other computer is connected to a different wifi … nope… someone can help me ?
On NullOnlineSubsystem (so no online service) server discovery only works in LAN as it use multicast packets for server discovery which work only in local networks. Outside (in internet) you need a service that lists servers, services like Steam, console online services (well not exacly sure on that one) provide such service and UE4 support them, so either you use them or your code your own solution (make server register somewhere and provide list to clients… maybe via HTTP?).
