Unable to start Unity Server for receiving Kinect input to android device

I am trying to create a remote VR game using Kinect and Google cardboard. To be able to get kinect input to my android phone, I am trying to create a Client-Server program wherein the client runs on the system which receives Kinect input and this is sent over wifi to my game running on android and this game instance runs the server script.

I found the this Server script SocketServer on net but the socketId returned (line 54) by NetworkTransport.AddHost(topology, socketPort); is always 0 and so I can't get my server to start. I can't understand what exactly the problem is here. I checked on unity's manual regarding how to create Server-Client scripts and I could not find anything.
