Error preArm 0x1 l:959 mapfailure

Hello, we have failed to unblock this error. Could someone unblock us?

All the calibrations have been carried out, yesterday everything was working, we could arm and disarm with the pro-tronik PTR-6A V2 remote control. Today we have several error messages:
-Error preArm 0x1 l: 959 mapfailure
-Gyro no healthy

Make sure you have a connection to a GCS and that GCS has connection to the internet.

Do you have a repeatable test case?
