spark disconnects just after take off and autoland

[dimi71]

Hello from Greece!!
I'm using the dji4 mod 2.0 and overall i'm very happy with my spark, and do long distances in fcc mode
The only issue is in the first battery usually, the spark disconnects from the controller right after take off and begin auto landing within 3-8 meters away from the home point without hovering above the ground and lands anywhere.
Then in 5-10secs connects again in the controller with no further issues.
In the last flight it was almost landed in the sea!!
I'm afraid to take off from my boat because of that.Can you help me what to do?

Post a flight log or two here and perhaps someone will analyze the logs for you.
