Copter changed automatically Auto to Stabilize and crashed

I am a newbie. My Quadcopter was in auto and undergoing a mission, changed to Stabilize mode automatically and crashed. Can anyone check the logs and see what really happen?

Do you have failsafe configured correctly?

Is it possible your receiver went in failsafe, and switched your flight-mode? In any case, as your throttle was at zero, when it entered stabilize the motors would have disarmed immediately.

This wouldn’t result in a failsafe report in the log if you don’t have the failsafe properly configured.

Look here, … -failsafe/

This is just a guess, your problem may lie elsewhere.
