Verify the network & time settings, then make sure the server is claimed (PMS must be able to communicate with plex.tv for claiming to be successful).
You should then be able to access the Plex server via app.plex.tv/desktop and via the NAS IP address (https://syno.ip.address:32400/web).
- Verify the network settings in the NAS
- IP address & mask
- Default Gateway
- DNS Servers - use a public DNS server such as 1.1.1.1 (Cloudflare), 8.8.8.8 (Google), 9.9.9.9 (Quad9)
-
Sync the NAS with a public NTP server
Control Panel → Regional Options → Time -
Follow FAQ 31: Reset / Reclaim PMS on DSM 7 (Not Authorized - Locked Out).
This will unclaim/re-claim your server. The metadata, database, etc. are preserved.
