Newbie to MyCloud - problems with login to MyCloud

Hi,

I have just bought a WD MyCloud EX2Ultra and tried to configure it. I thought I did well, but…
(Please correct me if I use wrong terms) I can login to MyCloud locally (from my laptop, inside my home LAN) using \devicename or IP. I set up users and emails. But I can’t log in to my WD from outside nor from app. When I try to files.mycloud.com it says “invalid email or password”. I am 100% sure the email is correct and I enter the same password as when I am on LAN.

Can the problem be caused by the same email for two users (actually for admin account and me as ordinary user) ?

Or maybe because I created some time ago (a year maybe) a MyCloudHome account with the same email ?

I am stuck. I don’t know what else can I do.

Make sure you have the cloud access account setup under the “Cloud Access” in your EX2 Ultra’s web dashboard, and not just the local NAS user account.
