I’d consult the users guide, if it doesn’t offer a working solution (troubleshooting section).
If not, I’d take it back asap and get a refund or new working cloud
The startup should take approx. 3 minutes and then the light should stay solid blue…
Make sure the unit is connected to your router with an Ethernet cable that is working (test it with a computer).
Try a complete reset: unplug the power, depress the reset button at the back of the unit, then, without releasing the reset button, plug the power back in and hold reset button for at least 40s.
If this doesn’t solve the red light issue, you should return or RMA your unit.
