I just set up my ne My Cloud Mirror today and everything went smooth to start with.
I got all the hardware and software installed and it worked fine.
I updated the firmware and it also updated the My Cloud mirror.
I took a deep breath and copy and pasted a small directory from my hard drive into a share folder I had created.
When I tried to copy and paste another small directory into the same shared file a box came up asking me for my Network username and password.
I tried every combination of usernames and passwords that it could possibly be but to no avail.
This same message came up when I tried to open any of the shares that I had created so I couldn’t access any of them.
The empty public shares could be accessed without a problem.
It appears that I can open that 1st shared file that I mentioned from above with my iPhone without a problem.
Please help as I can’t think what to do next.
