Native Mobile app on DMZ frontend server

I built a native app from service center on our platform server which is also being published to a DMZ front end server for mobile clients.
When installing the apk the mobile device it appears that it is trying to access platform server which is unreachable instead of the DMZ server.

How do I fix this?

Hi Anthony,

The app hails home to the server it's created on. If you want the app to reach the DMZ server, it needs to be created there (so from its Service Center).
