@Alcloud I take it you have a WD My Cloud and not a My Cloud Home since you say you have had it for several years. How do you have your My Cloud connected, is it to your router? What is the LED on the front doing and those on the back?
Are you on a Windows, Apple, Linux computer etc.
Have you rebooted your computer to see what happens?
If Windows does it show under File Explorer>Network? If not then see this and try it.
