Good news is the database migrations completed and there are no signs of database corruption.
Yay!
…
First, double check the network settings on the NAS. Make sure the IP address,
Confirmed correct.
mask
Subnet mask is 255.255.0.0 which, I believe, is correct.
default gateway…
Set to the IP address of my primary mesh access point to which my NAS is connected by cabling via a couple of switches in series. In turn, the access point is wired to my cable modem connected to my ISP.
Second, synchronize the NAS with a public NTP server. Synology Control Panel → Regional Options.¬
Connected to time.google.com, status = Normal.
Third, Follow FAQ 31: Reset / Reclaim PMS on DSM 7 (Not Authorized - Locked Out)
Consulted
to reclaim the server. You’ll uninstall PMS,
Uninstalled “Uninstall only”.
then re-install the same version (1.41.6.9685), using the Plex Claim Token method.…
Done.
If successful, you’ll see a “successfully claimed by” message.
Seen. Claimed by my Plex persona.
Then try and login directly to Plex using the NAS IP address, http://ip_address:32400/web. Hopefully you can login, reach server settings, see your libraries, etc.
Logged in. Can play music using the Plex for Max and the Plexamp for Mac clients. Yay! A few issues detailed below in ‘New observations’.
If the claiming fails note any error messages on-screen and pull a new set of log files.
No error messages observed.
FYI, I saw all the MediaProviderManager error messages. Not sure what is causing those. It could be that the server is unclaimed and/or having problems communicating with plex.tv.
Q: Since I’ve got the new Plex Media Server claimed and I can play media files locally, may these historical error messages now be ignored?
New observations
I now have two sets of libraries (each having a “music” & an “audiobook” libraries) corresponding to libraries created before the DSM update (set A) and another created after the DSM update (set B). Set A is operational while set B is not (as expected).
Q: How do I remove the libraries in set B from the Plex & Plexamp apps?
Libraries in set A seem not to have “noticed” the new media files added during the inter-regnum. Reading Scanning vs Refreshing a Library and noticing that ‘Plex for Mac / Settings / <my_server> / Settings / Library’ has ‘Scan my library automatically’ enabled and ‘Scan my library periodically’ (with interval ‘daily’) leads me to the assumptions that the new media folders:
- Aren’t watched by the automatic scan subsystem (since the new media “snuck in” and wasn’t registered); and,
- Will be scanned during the periodic daily scan.
Q: Are my assumptions correct? If not, please clarify.
Q: Am I correct in understanding that audio libraries can no longer be accessed via the Plex for iOS & Plex for iPadOS apps and instead can only be accessed via the corresponding Plexamp apps? If so, an interesting spec decision…
Again, as always, thank you so very much for your assistance!
