Today I had the same error message come up. I flew 6 missions all at 80 meters alt 350x350 m2 and 6 missions flew fine. I went to fly a 7th and had this same error message come up along with “landed” being shown on the screen upon opening the mission. My boss is getting frustrated with me over these issues as I need to get this area mapped and we literally only spoke to you guys about buying your software yesturday and are seriously reconsidering that after these constant errors. I need some clarity on how to resolve this as I literally had it operating fine then moved 200 meters away to another spot and got the internal error message.
The same problem with new phantom 4 pro v2. Actually I made a similar flight, and the next one never allowed me to fly.
I would suggest the following,
Check this interactive map in order to see if the area is inside a no-fly-zone.
Could you do a quick check if the Maximum Altitude setting in DJI GO 4 is too restrictive?
