Android Wifi Local Multiplayer

Hello, I’ve already created a shooter game . Now I want to set up local wifi multiplayer. But, I’m facing a lot of problems. When I create a session and join its work on my pc but when I package the project and run it on android and I host the game but on my other phone no server found. How can I fix the problem?? Please Help. I’m searching in ureal engine documentation but there is no good documentation on android LAN . Advanced thanks.

Did you add android.permission.INTERNET to your permissions? This is required if you want to use internet in your application.

This can be done under ProjectSettings->Android->AdvancedAPKPackaging->ExtraPermissions
