How to connect android device to server?

Hi,

I have been researching on the internet for weeks trying to find a tutorial or some help. I want to know how to get an android device (Nexus 9 tablet) to communicate to both a listen & dedicated server through blueprints (preferably). I know this is possible, as many people have said they have achieved this, however no one offers a solution or help on how to get this to work. I’ve tried many things with no success. Besides configuring the project to build for android, is there a specific setup this requires?. I can host and join a session no problem on PC. However, nothing is working on android.

Thanks
