Media library has disappeared after the latest app update

Server Version#: 1.41.6.9685-72009685
Player Version#: 2025.15.0 (1053)

My router was down for some time, and after getting it back up and all my devices connected I am no longer able to see any of my files from Plex Media Server. The files are accessible from my Finder on MacOS. The files are accessible from other software applications as well. For some reason, Plex does not give me the option of adding ANY library, folder, or files. My library is not available on the Web App or iOS or Android clients.

I have restarted everything: the NAS, the Plex Media Server (stop and started the container), checked for a VPN on my Mac and the NAS and there is nothing. DDNS was fixed within the Synology setup, so external access works from the URL provided by Synology. The SMB service works fine as well, and I can see and access the files.

Is this a bug?

Look at the plex logs. If it says cannot start because PMS is already running, restart the machine PMS is installed on, not just the container.

I’ve restarted the machine, but will do so again.

Restarting the NAS did not work.

So from your description PMS server settings are completely inaccessible? Or is it accessible and your problem is that it won’t add your media?

Im asking if the Plex Server is even running and that you can access it?

Are you able to access the PMS web interface by ip:port directly?

The Plex server is running, it won’t let me add any media though. I can access the Plex Server from the web, and the clients do connect to the server, but the media is not available and there is no option to add the media either.

Yes. I’m able to connect http://ip:port

This is highly unusual. I’ve never heard of not being able to add media.

Can you screenshot what you mean? Or how are you adding new media? Are you going to the library and adding the path to the media? Is that window not popping up? Check your ad blockers as I heard from someone that some windows were not loading due to their ad blocker.

What are the paths you’re using for the library mount in the container?

The Plex Media Server is not listed under authorized media devices. Here are the other screens.



So that’s what it looks like when you don’t have a PMS server tied to your plex account. Did you claim the server? You can only claim the server when you access it via local network. Find the local ip of your synology NAS, then add :32400, for example: 192.168.1.2:32400

@vern211

Is the NAS running DSM 6 or DSM 7?

In your first post, you mention “stop and started the container.”

In your post above, you show a “native” install using Package Center.

Just to be clear, you are using the Package Center installation and not Docker/VM/etc., correct?

Given your last post, it appears the server is not claimed.

If using the Package Center installation and running DSM 7, suggest you try the following:

  1. In Synology Control Panel → Regional Options → Time tab, synchronize the NAS with a public NTP server. This ensures the NAS has the correct time. If the time is too far off, then claiming will fail.

  2. In Control Panel → Network, configure the NAS to use a public DNS server such as 1.1.1.1 (Cloudflare), 8.8.8.8 (Google), or 9.9.9.9 (Quad9). Some ISP DNS systems have trouble resolving plex.tv IP addresses for some reason. If the NAS cannot communicate with plex.tv, claiming will fail.

  3. To reclaim Plex Media Server, follow FAQ 31: Reset / Reclaim PMS on DSM 7 (Not Authorized - Locked Out).

If the claiming process is successful, connect to Plex using ip:32400/web. You should be able to login, reach server settings, etc.

Thank you! I followed all of those steps and that seemed to do the trick.
