My brand-new EX2 Ultra, right out of the box, never exits the “powering up” stage. The blue power light has been flashing (rapid flash, not the slow flash) for three days now. I’ve tried unplugging it for 1 minute and plugging it back in, I’ve tried the 4 second reset, and I’ve tried the 40 second reset. Both HD lights are solid blue, and the router knows it’s there - it has an IP address, and the name “MyCloudEX2Ultra.” Attempting to reach it via the IP address results in " 192.168.0.155 refused to connect." I’ve contacted Support, but it seems to take them at least a week to respond. I’m wondering if I should just pack it up and return it to Amazon.
Try http://192.168.0.155 and https://192.168.0.155 . Usually It will present you with a login but won’t let you in saying something like “Device is still booting up”.
Or on both links you got refused?
Correct. Refused on either variant - but AFAIK, both resolve to just the IP address anyway. (http://mycloudex2ultra.local/ doesn’t work either…)
Yes, but different ports (80 and 443).
Good to know; thanks. Support wants me to give it a week… I’m sure that’s delaying the inevitable, but they’re in charge.
And… it’s been a week. I have to confess that I am absolutely baffled as to how any modern electronic device could take up to a WEEK to boot; I think they were just trying to delay the inevitable. At any rate, I guess there’s no fix because it was always DOA. It’s going back.
Its defective. Return it and get a new one (or a Synology).
Thanks; I already did both of those things and asked the mods to close this thread. 
I do think they should dispense with the “just wait a week for it to boot…” advice, especially in cases like mine where everything else works (fast router, NAS recognized and IP address assigned; server drives scanned and approved.) It’s not great advertising.
I have this exact same problem too. I have had the drive a couple of months and it just sits there refusing to boot, despite being visible on the network. I sent off the unit to get the data recovered but the cost was at least 5 times the cost of the EX2. I figure I’m going to have to wave goodbye to my music and video libraries. Unimpressed. Any clues would be gratefully received.
The drives are probably still good. I’d try cloning them and looking for a cheap used EX2 on ebay to plug them into… or an old MyCloud Mirror. The format is, as far as I know, the same for all WD mirrored drives. I wound up plugging the drives back into the old MyCloud, backing that up to a USB drive, and then transferring that data to my new Synology drive.
Thanks TheOtherJim, that is sound advice. I’m on it.
