Direct IP working but Find Session Not

Hello everyone…
I have a problem with creating a simple multiplayer game for mobile devices.
Like Multiplayer Shootout project sample i made a menu for hosting and joining game.
Hosting section works good and session created successfully with Use LAN enabled and level opened with listen option and everything is good.
but problem is here when other device wants to find session, i made a menu for that like multiplayer shootout project sample and i know Find Sessions node run On Success but there is not any sessions found !! as the Create session Use LAN is enabled in Find Sessions node too. (i tested both true and false for Use LAN in both create and find sessions nodes)

for test i created button and run a console command Open [OtherDevice IP] and i could join to other device and everything was good.

I was surprised when i packaged game for windows for testing and run on a single machine two times one as host and other for joining everything was working perfect but only on single machine when i tested on two pc nothing happened and no session found.

All devices(Mobiles and PCs) are connected to a ADSL Modem router with wi-fi connection.

check if it’s networking problem, do other LAN games work for you? I mean do they see the LAN sessions

thanks for your reply… I don’t know about other games for now i’m currently downloading Blueprints project sample from Learn tab in EpicGames Launcher to test that, i hope that project has multiplayer options… is there any other multiplayer projects in marketplace learn tab ?
I test it with 4.9.1 but same results

I tested with direct cable connect between two PCs still just direct IP working…
I tested with Red Alert 3 game network playing feature when direct network cable is connected PCs can see each other in Red Alert’s network list but couldn’t join each other with time out connection error…
I tested Red Alert 3 with wi fi using my adsl modem but they couldn’t see each ohter in Red Alert 3’s network menu…
I don’t know what happened but in mobile devices i could see sessions in server list menu !! but they couldn’t join each other !!

the same problem here, not solved?

I have this problem too…can someone help us?

Same problem please help
