Hi, I was having the same problem on my Mag250 latest Software Uppdate from Sept 2018 with Blue Line loading to 80% then Black Screen and back to Checking Image Screen with Loading and constant loop, always same thing over and over and over.!!
The Solution Fix from "cossan" solved my issue...In the inner portal go to settings/system settings/network and whatever option you use for your internet change from " auto-DHCP " to " auto-dhcp/manual dns ". And on " manual dns" you put " 8.8.8.8" save and reboot.
@Cossan, thank you
