Unable to switch to any AUTO modes with Copter 4.0.4

Recently I upgraded my Fixhawk from 3.6.9 to 4.1. Test flight was OK until I switched from STAB to POS_HOLD mode. Nothing happened, copter was onli in STAB mode. The same with RTL.
I downloaded log but didn’t find anything I could unveil the ground of my problem.

Autoanalyzer only show this:

Could somebody help? Link to log file.

Your number of GPS sats is low and your HDOP never goes below 1.28 - so no 3D fix.
The craft doesnt know where it is, so cant use a mode that relies on GPS.
If you want to ensure a 3D fix before takeoff you can try arming in Loiter mode, or set:
FENCE_ACTION,3
FENCE_ALT_MAX,120 <- suit yourself or local law
FENCE_ENABLE,1
FENCE_MARGIN,5
FENCE_RADIUS,600 <- suit yourself or local laws
FENCE_TYPE,3
And this will ensure you’ve got a good 3D fix before arming.

Thanks for analyse :grinning:
I thought if the GPS status is 3 it means it has an 3D fix. I was wrong on it.
