Can't login, from Win 10 desktop, to a MyCloud.com account

I get “No device Available” message. I thought I might have to go to Cloud Access to fix this and got Failed to update devise message (400068) when I attempted to resend the Code. It seem as though this “User Account” is no longer connected to my WD Ex4. Other users of different accounts have no problems. Advise Dozo??
