I was copying files onto MyCloud and it suddenly died. It stopped responding. I tried unplugging it and replugging it and it didn’t connect. It didn’t show up in my Orbi list of the attached devices. The green light network light is blinking but the device didn’t show up on the list of the attached devices.
