The My Cloud Desktop application has been end of life (EoL) since 2016. It was a recent firmware update that finally broke the functionality of the software.
The single bay My Cloud units are not really designed for a business environment. Generally they are aimed at the home user.
WD has decided that the MyCloud.com web portal is the main method for remote access and for users to create sharable links. Or one can use the WD app for iOS or Android to access the My Cloud remotely or create shareable links.
As explained elsewhere today in a similar thread complaining about the My Cloud Desktop not working, one can try to downgrade the My Cloud firmware to see if they can regain the use of the My Cloud Desktop program.
This is mostly a user to user support forum.
One can request WD reinstate the functionality of the My Cloud Desktop software in the Cloud Ideas subforum.
