My EX2 Ultra unusable after OS update - is there a way to get it back again

My Cloud OS 5 Personal & Network Attached Storage My Cloud EX Series

  1. So just received EX2 ultra, and following instructions installed it
  2. dashbord offered firmware update - what I allowed
  3. dashboard offered OS upgrade - what I allowed
    Now my EX2 is not usable normally and safely - dashboard is inaccessible (shows error 403) I can’t access any configuration and safety tools. User files are accessible though through file browser, but any administration is blocked.
  4. I contacted WD online chat support and received recommendations do 40s reset, what I did - nothing changed. EX2 administration is still inaccessible - shows HTTP ERROR 403

So is there any way to get it back or I should return product as faulty?

@gija the following article explains HTTPS ERROR 403 and how to access the Admin UI dashboard.
Basically the My Cloud and Computer must be in the IP address ranges defined in the article.

Ok, thanks for response,
but

  1. how I can influence which address dhcp gives to Ex2 - it is beyond my control, I’m not the admin of our network?
  2. it seems serious bug in OS update, because prion OS update it should check if IP address is in valid range for new OS to function normally
  3. is there way to revert to previous OS if I have no way to influence which IP address EX2 is given?

It’s not the only bug - better you switch to Synology DS220 for just a few bucks more and do yourself a favour!

Here is a list of some more bugs of the OS:

I would fire the development department!
