WebDeviceLocation : Could not determine the device location: Timeout


I’ve started the XOJO (2015R3) Web Example “MapViewer”.

But when I connect to the server with my Android Phonedevice (Android 4.3) using Chrome (V. 46.0) and click on “Get device location” I get an error:
“Could not determine the device location: Timeout expired”

In the phone settings I’ve enabled Google location services - and Google Map works, so I receive GPS signals.

And in Chrome I’ve allowed my server’s domain to access my location
(Chrome: settings - Websites settings - location - allow domain)

I was asked “Allow this site to access your location” - and I’ve answered “yes”

I see the same problem with Firefox for Android.

Any ideas on how to make this work?

Does it work on other devices?
