Lost connection to my Plex libraries

I seem to totally lost access to everything, as far as Plex, running on my Synology, is concerned. All the files are still accessible however, through DSM on my iPad.

I updated DSM this morning, after which time all my stuff vanished from Plex. I’ve not changed anything else. What are the steps I need to take my get back on an even keel?

What kind of update are we talking about?
Did you upgrade DSM from version 6 to version 7?

I did some digging and it’s all back. The DSM update made PMS on the NAS incompatible, so I had to uninstall it, claim my server token from Plex and reinstalled.

I upgraded to 7.2.2 from whatever it was before. Thanks again.

Did you get the special 7.2.2 version for DSM?
