Adroid player lost content external php page

Hi there,

I have for the football club a xibo installation with 2 android players.
I run a schedule with 12 layouts, tree pictures, 2 video’s and 7 webpages.
For all layouts i have a default background and static regions.

The seven php webpages are loaded in a region in the layout.
De php pages are coming from an external webhost (http).
When i start the android box the webpages are shown in the region.
But after a 3 circle runs on the player, the external content is not shown anymore.
After i reset the android box same … 3 cicles … content external webpage gone …

Anyone a solution ?
