How to Test Online Multiplayer on Mobile

Hello

I’m having difficulties testing online multiplayer from UE4 to mobile (Android only as of now), i got something setup and it work on the editor but i cannot get it to work on mobile. I did change the the onlinesubsystem to " Null " on the DefaultEngine.ini and also try changing the join session node to command console node, tested it on stand alone window and on android im launching it through the editor but still noting work do i need to package the game ?. I’m fairly new to the whole online system and that make me think im doing something wrong or missing something. I’m hopping for some guidance or tip, i already watch to video series and UE4 Document related to this subject but still noting work.

Video Series Watch

and

Thanks in Advance.
