hi first of all i am amateur so don’t talk super expert please, thanks.
second is a weird problem that’s not make sense to me and i got a real headache of this:
i am making a vehicle game that will play on android but i cant connect it in windows either 
, session is creating but joining is a dream, and the interesting point is i made it a week ago but by some stupid reasons i deleted whole blueprints and i don’t know how i did this!!! so i’m totally confused.
i just want the lan not steam (and i used simple session not advanced one)
i watched every single video about multiplayer in youtube and also read the documentation
can you guys simply explain how the session work? (i mean the variables and arrays and session nodes)
and the third thing is HUDs. i don’t know why hud widget is showing on server only, clients just showing non variable things in the hud widget like images (its game mode HUD)(this was before i destroy the sessions blueprint)
thanks for reading, sorry for bad english 
Hey man. the question you are trying to ask is too general and make it impossible to analyze and find the correct answer for you. kindly, recommend you to do more research and more learning about the whole multiplayer system in UE4.
you mentioned you already did watch lots of tutorial. but just try these two resources too. everything you need for you scenario is already covered here. try to watch the video and then after that read the doc. both are super useful thanks to their creators. Cheers!
