For some reason I can't make multiplayer game work on mobile (Android 5.0), built with Phonegap Build (It doesn't work neither with Crosswalk or WebView. It always says "Multiplayer not supported".
Default examples from Contstruct 2 such as Chat Room don't work too. Here is an example of chat room: https://www.dropbox.com/s/hu7elivgobtp8kc/Multiplayerchatexample-debug.apk?dl=0 (I used a simple webview in it). C2 is latest version, no 3rd party plugins.
What could be wrong?
