Cannot reclaim Plex Media Server on PR2100 following Plex password reset

If you're unable to reclaim your Plex Media Server on your WD My Cloud PR2100 after a Plex password reset, you're not alone—this is a common issue, and it can be frustrating. The reclaim process can get stuck or fail for a few reasons, including credential mismatches, cached settings, or local authorization issues. Here's a comprehensive breakdown of the issue and how to resolve it.

Why This Happens

When you reset your Plex password, your authentication tokens also change. If your PR2100 is still using the old token or cached data, it can’t connect properly with your Plex account, which prevents you from reclaiming the server.

Symptoms

After logging into your Plex account, the server shows as “unclaimed.”

You’re unable to reclaim the server, even though you're logged in.

Reclaiming the server times out or gives an error.

The Plex server on your PR2100 keeps redirecting to the setup page.

"Not authorized" messages when accessing settings or libraries.

Step-by-Step Fix

1. Unlink the Server from the Old Account (If Possible)

If you still have access to the Plex dashboard online

Go to Settings > Devices.

Find the PR2100 Plex Server in the list.

Click Remove (this unlinks the old server from your account).

2. Access PR2100 via Dashboard

Go to the WD My Cloud dashboard in your browser.

Navigate to Apps.

Locate Plex Media Server and stop the app temporarily.

3. Delete the Old Plex Configuration

To fully reset Plex on your PR2100, you’ll need to remove or rename its data folder:

Important: This will reset your server settings and libraries, but your actual media files will not be deleted.

Steps:

SSH into your PR2100 (enable SSH via the dashboard under Network settings).

Use an SSH client (like PuTTY) and log in as sshd or root (credentials are set in the dashboard).

Navigate to the Plex config directory. It’s typically:

/ shares / PlexMediaServer / Plex Media Server

Rename the configuration folder to back it up:

mv "Plex Media Server" "Plex Media Server Backup"

4. Restart Plex

Go back to the WD dashboard.

Start the Plex Media Server app again.

This will create a fresh configuration folder.

5. Reclaim the Server

Open Plex in your browser (either from the WD dashboard or via

Log in with your Plex account.

The new setup screen should now appear, allowing you to claim the server.

If prompted with a reclaim token, you can manually do this:

Use the following command via SSH:

Replace claim with a valid claim token from:

Then restart the server again, and it should bind to your Plex account.

Additional Tips

Clear your browser cache or use an incognito window to avoid redirect or caching issues.

Make sure the PR2100 firmware and Plex version are up to date.

If you’ve customized your library structure, consider backing up the original "Plex Media Server" folder before resetting.

Conclusion

Resetting your Plex password can disrupt the token-based authentication used by devices like the PR2100. If your server becomes "unclaimed" and won't re-link, a full reset of the Plex Media Server app configuration is often the most reliable fix. After clearing the old data, you can reclaim the server with a fresh token and get your media library up and running again.

If the problem persists after these steps, it may be worth reinstalling the Plex app via the WD dashboard or reaching out to Plex support with detailed logs.
