Metadata agent not working anymore

Plex Media Server

Hi, I updated my Plex Server on my Synology, maybe 2 weeks ago, and I started noticing that the metadata information is not refreshed anymore.

I have been watching latest season of the Lioness: first 2 episodes contain all the usual information, but the latest 2 don’t have anything.

First I thought that maybe the server is down or something, then I noticed that the metadate setting have been updated and now there is two different pages. Maybe that is the reason.

Anybody else having similar issues?

Server Version#: 1.43.3.10896
Player Version#: Latest viewer that is available for the Google TV

Let’s see a screenshot of your filenames and directory structure, please.

Path is “Special Ops Lioness\Season 3\special.ops.lioness.s03e04.mkv”

I think its something else, because if I try to re-match old TV show or movie, the match windows is totally empty.

Please post your server logs. This sounds like a DNS issue and you are not able to connect to plex.tv

I had this last week. It has since started working again. While it matches new content adequately, some old content is now mismatched, mis-postered, or unmatched entirely.

To add to @napolij’s information, some ISP DNS servers have issues with plex.tv hostnames. That is why you see people recommend using public DNS servers.

Here’s how to configure DNS on Synology DSM 7 (DSM 6 will be similar). Synchronizing the NAS clock with a public NTP server is also a good thing. It ensures the NAS time is correct and serves as a basic Internet connectivity test.

DNS Settings

  • Synology Control Panel → Network → General tab.
  • Configure the NAS to use a public DNS server such as 1.1.1.1 (Cloudflare) or 8.8.8.8 (Google).

Synchronize NAS with NTP server

  • Synology Control Panel → Regional Options → Time tab
  • In Time Setting section, chose Synchronize with NTP Server
  • Pick a server from the drop down list, then click Update Now.
  • You should see Status = Normal.

Found following from the logs:

Aug 24, 2026 21:38:33.757 [140712782666552] WARN - [HttpClient/HCl#87] HTTP error requesting GET https://metadata-static.plex.tv/7/people/795a83a6ca3f77692c5ec65b29e1db9f.jpg (7, Couldn’t connect to server) (Failed to connect to metadata-static.plex.tv port 443 after 6012 ms: Couldn’t connect to server)

Now I need to figure out who is blocking that :smiley:

Some additional things to check/try:

  • If using a Pi-hole or similar ad blocker, make sure plex.tv is whitelisted.

  • If the Synology firewall is enabled, try disabling it temporarily.

  • Power-cycle your router. When it is back online, reboot the NAS.

Issue resolved. I’m using Pi Hole, but that doesn’t seem to block the plex address. There was something wrong with the system time, after that was fixed, Plex started working again :smiley:
