What could cause this image transfer problem?

[F4 Phantom II]

Hi everybody,

For the second time now i've encountered a strange issue.
Normally in the country side i can go about 100m up and 1200m away, thanks to the MOD and a windsurfer.
Now in a rather huge suburban park it says "no image transfer" in DJI Go at about 30m away, wifi and RC are at full bars, gps seems to be gone.

Could this be a geofence or something? I know this area is often used as a take of place for large balloons used for pleasure flight.

"no image transfer", your not getting a picture (live view)?
Are you getting telemetry?

"gps seems to be gone"? you must not be getting telemetry, but you must be if you can see your remote signal.

Let us know.
