Hi Daniel,

This usually happens when there is no connection to the server, so there is no entry in the server log (service center) about. It happens when the app is closed in the phone and I tried to open it (and there is no connection to say, the internet), probably because the first thing that happens is the apps checks if there is a new version of itself. 

That should not be the reason, what might be is that you execute a server action in the OnApplicationResume or on the display of the screen. You should always check if there is an internet connection before you call a server action or access server entities.
