RED Devices not working any longer

Hello,

we are investigating issues with our RED devices which are used in occasionally projects. They used to work a couple of months ago.

The system is booting into system - router both green and go then to system (red flashing) - router (green) - internet (green flashing) 
and then starting with an earlier stage.

Thanks.
