Folders & files Not Visible with Admin login

Some more info : On the Dashboard under the Yellow bell Icon I see a Message “Network Link Down” but my network is working fine for everything but WDMyCloud
I’ve also tried to download WDAcces : it does just nothing !
More info again
I have 3 Windows 10 Machine on my network
An all machie I’m admin and I have the same Credential
Finaly on my third machine I was able to see the full content on my drive
But it clearly shows that the behaviour of the WDMycloud drive on a Network is not stable and reliable
I’ve seen this post and I will subscribe to it
