Mac system not finding EX2 as connected drive

I have a Macbook Air running Big Sur with an WD My Cloud EX2, when I go to finder the EX2 is not showing up as a connected drive even though I can “see” it by using the web. I am a new user to this. any suggestions

it is possible you may need to click on Apple finder and select show network devices
That trips me up a lot when setting up new system

Finder on your Mac , choose Finder > Preferences. Click General,
