The My Cloud Desktop program has been End of Life (EoL) for a while now. After a recent WD firmware update (appears to be v2.x firmware My Cloud users) some users (both Windows and Mac) can no longer use that application to access their My Cloud remotely. Unfortunately one is now being forced to use MyCloud.com web portal for remote file access using Windows or Mac operating systems (or using insecure FTP) on their computer.
Edit to Add: Just noticed that the My Cloud Dashboard no longer properly accesses my first gen v4.x My Cloud running the latest firmware. It no longer lists users to select from when setting it up either on a local network connection or remotely. Guess WD finally killed off access with this program on the first gen with the latest v4.x firmware.
But then what can we use instead of it?they just kill it but what can we use now then, i have it install on windows and was working very good but now i cant get access anymore, i tried WD discovery but i dont think is the replacement Helpppp
WD didn’t “just kill it” recently. WD finally killed the Desktop program over a year ago with a firmware upgrade to the single bay My Cloud line. The Desktop software hasn’t been updated since 2016.
As previously indicated WD wants people to use the MyCloud.com web portal or the My Cloud mobile apps for iOS or Android for remote access.
For local network access to a My Cloud the WD My Cloud Desktop program was never needed. For local network access one uses Windows File Explorer, Mac Finder or a file manager app for iOS or Android.
The multi bay My Cloud models may have additional methods of remote access. The single bay My Cloud model does offer the insecure FTP method of remote access. There are possible options for secure remote access to the My Cloud using firmware hacks (SFTP or SSH).
But perhaps the better method would be to setup a VPN server on the same network as the My Cloud. This however generally requires additional knowledge and skill to configure properly. Some consumer routers (Asus and others) typically offer the VPN server built in to their router firmware. By using VPN you would be able to access the My Cloud just like you were on your local network. Otherwise one is limited to the few options for remote access that the My Cloud is limited to.
