Hi trumpy81. Thanks for your suggestion.
Now that I’ve finished for Christmas I thought I’d have another look at this. No joy with the reboot. No joy with deleting plexmediaserver.pid and Preferences.xml. It also occurred to me to remove registered devices - no joy.
I also had the problem that my movies metadata had stopped working, for no apparent reason.
So I thought I’d do a full uninstall (How to uninstall Plex completely from my Synology NAS?) and reinstall. STILL no joy - I still get the “unclaimed and not secure” message.
Any other ideas? Could this be a client-side problem?
