@Krit_Murray I have been trying different UN and PW’s all day to try and figure this out. This is what I finally got to work. I am the admin of My Cloud, name is horace, I do not use a password to get into my My Cloud for any shares.
After turning off Public to my Horace share and going back to File Explorer and clicking on that share when the box to enter Credentials came up all I entered was User Name, horace, password was left blank, clicked OK and my Horace share opened.
You can try this and if it doesn’t work check credentials on your computer and see if anything is there for WDMYCLOUD. If there is you may have to delete it first. See example image below.
I hope this works for you.
