Plex library suddenly not showing despite working yesterday and no system changes

If I may assist ?

I see you are using DSM .

I looked at your Preferences.xml. The Token field is empty. If you edited this – thank you. If it’s really blank then this is why the server cannot connect.

To remedy this, the Package (SPK) file contains everything needed to reattach your server to your account.

Here are the instructions, with screenshots

Please advise your results.
