Request for Assistance with Plex Media Server and Possible Server Reset

I am writing to request assistance with an issue I am experiencing with my Plex Media Server installed on a Synology NAS. Recently, I have encountered a problem where the “Add Library” button is missing from the Plex interface, and I am unable to add new media libraries. Despite following troubleshooting steps, including restarting the server and checking for updates, the issue persists.

Given the complexity of the problem and its impact on my media management, I am considering performing a complete reset of my Plex Media Server to resolve the issue. However, I would appreciate your guidance on whether a server reset is the best course of action and if there are any specific steps or precautions I should follow to ensure a smooth reset process.

Here are the details of my setup:

Plex Media Server Version: 1.40.5.8921-7000

Synology DSM Version: 7.1.1.42962

Issue Description: “Add Library” button is missing; unable to add new libraries.

If a server reset is recommended, please provide instructions on how to proceed safely. Additionally, if there are any alternative solutions or further troubleshooting steps you recommend, I would be grateful for your advice.

You may have solved this already, but try the following:

  1. Open DSM > Package Center and uninstall Plex. Make sure you Uninstall only!
  2. Reboot the NAS
  3. Install the latest package for your NAS from Plex downloads.
  4. Open Plex by typing http://NAS-IP-Address:32400
  5. Make sure the server is signed in and claimed in Plex Settings > Server > General
  6. Go to Plex Settings > Server > Libraries and add any libraries etc.
  7. Don’t forget to check the Manage Recommendations settings for the library/ies.

Fingers crossed, that should resolve your issue.

If you still wish to remove Plex from the NAS completely, then when uninstalling Plex choose the option shown in red, Erase all of Plex … (bottom of the list of options)

You can then proceed to reboot the NAS and install Plex from scratch.

it worked!!
thank you for your help
