WD Cloud and Plex

I cannot find a way for plex to see my WD cloud. I am not technically minded but if anyone has any simple instructions I would be grateful.

it looks like there have not been any responses to this question. I hope someone responds since I have the same issue. I loaded the Plex server on a PR2100 and loaded the client on a Nvida and a Windows machine. None of the Plex clients seem to see the server. I invested in the Plex pass. I just need some basic training or direction where to do some self education. The How-To-Geek newsletter listed a lot of benefits of using Plex overr Kodi so my interest is peaked for another try at this. For some reason my HDHomeRun server can be seen by my HDHR clients on these machines so I am assuming it is operator error on my part. I need to do some reading.

After a very little research, I found this. It is a good place to start: https://support.plex.tv/articles/204604227-why-can-t-the-plex-app-find-or-connect-to-my-plex-media-server/
