Hello I have setup the Plex Server in my Cloud. It works on my phone and my computer. But It does not work anymore under the chromecast with google TV. I tried to delete the Plex App, redo the configuration process in my cloud and nothing works. It seems the chromecast does not see my cloud online.
Do you have a My Cloud device or a My Cloud Home device? They are not the same devices. If you have a My Cloud Home device see the dedicated subforum for that device were users who are more familiar with it may be able to assist.
