Not Receiving Data After Power Cut

Following a power cut I've restarted the CAD, I'm not receiving any data (as reported by the Bright App) I I can't get any current consumption data.

It's been a couple of hours now and a couple of restarts for the CAD

The device shows it's connected on the screen, but it's actually stuck "chatting to the meter"

Octopus Mini & Original IHD not connecting either.
