I've tried your code on my android phone (Android 5.0.2) and I got an error as expected

Connection Failed
(ErrnoException) android.system.ErrnoException: connect failed: EHOSTUNREACH (No route to host)

no idea ?

Erel · Mar 21, 2016

I'm not sure that I understand the question. It says "failed to connect" in the logs.

Why aren't you posting the logs from the IDE?

Anyway there is nothing that you can do about it. The connection status comes from the native layer.

M. Giray Ozkan · Mar 22, 2016

by the way, there are many things that possibly go wrong. 3G connection stability, 3G network provider structure, tcp port availability, modem port forwarding issues etc...
