Problem just started today where the Plex server is not found across multiple devices (Roku, Android, Desktop). Whenever I go to the site on my desktop I get the "Get Your Plex Media Server" in the middle of the page and on the right it just says "looking for servers" and constantly spinning.
Just update the app on MyCloud Mirror thinking this might fix it but it has not. Updated to version 11134803.
Rebooted the NAS to no avail.
