No PR2100 Server Since Password Change

Server Version#:

1.42.1.10060

Since the recommended password change, I have been unable to re-claim my PR2100 server. Uninstalled/reinstalled all apps and server software (Windows web/Windows App/Android Phone/Nvidia Shield), even tried it on a Linux machine. Nothing. The reclaim thing under Settings/General just won’t pop-up. Changed ethernet cables too, then back again. Nothing. Any help would be appreciated. Very frustrated.

Are you on the same network as the NAS when trying to claim the server?

Also, there have been reports of Plex on WD NAS not automatically starting after an update.

On the WD, make sure Plex is running.

Then point a browser window at the IP address of the NAS.

For example, if the IP address is 10.1.2.3, use http://10.1.2.3:32400/web.

Appreciate the quick response FordGuy61, but I have done all those things numerous times and it’s the same network. Still frustrated.

One last question?

Have you tried.

  1. Close browser
  2. Open browser fresh (no tabs)
  3. Open Incogito tab
  4. Now open the PR2100 by LAN IP http://10.1.2.3:32400/web

After you claim it, close the incognito window
Reopen normally

Yes, tried that several times, plus rolling back the Plex Server software. What gives? Was the Plex hack worse than what’s being stated? I notice on here others are having the same issue w/ other servers too.

See if Plex Media Server is responding.

Point a browser at https://wd_ip_addr:32400/identity ← use the real IP address of the NAS

You should get back one line of XML information containing claimed="0" (unclaimed) or claimed="1" claimed.

Example:

<MediaContainer size="0" apiVersion="1.1.0" claimed="1" machineIdentifier="a6.....

No connection. Firefox says not secure and MS Edge says the connection was closed.

If you get a warning that the connection is insecure, go ahead and continue to the site. You’re connecting to your own server.

Also try http instead of https.

If Plex Media Server is running, then it should respond.

The http worked. 0 claim.

Good. That confirms PMS is running and is unclaimed.

Now try using http and a incognito browser window to login.

http://wd_ip_addr:32400/web

If you can login, click the wrench icon in the upper right and see if the server settings are available. If so, try to claim the server.

Logged in. No server to claim. Last night I tried Resetting Customizations which stated a redirect to setup and claiming a server. That just spun around and around. What a mess.

So you saw the initial setup screens? Try again. If you get as far as setting up libraries, do not add any, since they already exist. If you get stuck on a page that is just waiting/spinning, give it a couple of minutes. If it does not progress, try reloading the web page.

The last thing I know to try is the User Credential Reset utility.

The NAS must be running OS5.

You’ll SSH to the NAS, run the script from the command line, and include a claim token from https://plex.tv/claim.

Plex Media Server must be stopped at the time. I’m not sure if the shell script will stop PMS on WD NAS. If not, it should prompt you to stop it manually.

The README on the GitHub page has additional details.

Success! Thank you, FordGuy61. Not sure how I got it, but tried Linux and gave up…. too rusty. Used Putty and tunneling and it finally clicked. Thanks again. You’re the best!

FordGuy61 Can I get some help on this issue as well. I changed my plex password based on a email from Plex on a possible breach. My Plex server runs on my WD MyCloudEX2Ultra. It runs OS5. Other not plex apps can see the server but plex Web, windows, and app can not see it while on the same network. I have tried to go thru my NAS IP address/plex web, relog on, and reinstall with no luck in getting to Sever settings. Please help. Here is what I see with Identify address.

I have tried to follow the above steps but I do not know what you mean by SSH into the NAS? I see the enable SSH option in OS5 but I am not sure how to use the github info to SSH in? Please help

SSH is used to open a terminal session to the NAS.

If disabled in OS5, you will need to enable it.

You will also need to know the admin/root password for the NAS. I’ve never used a WD NAS, so am not sure how to find or set the default admin password.

If things work the same as on an Ubuntu system, it will go something like this:

Step 1: Stop Plex Media Server

Step 2: If on a Mac or Linux box, use a terminal session. If on a Windows PC, open a command window to get to the C:\ prompt.

Enter ssh user@IP, where user = the username you use to login to the server and IP = the IP address of the server.

You may see some text about “the authenticity can’t be established.” Enter yes to continue.

You’ll then be prompted for your password.

Step 3: Change to the desired directory

cd /mnt/HD/HD_a2/Public

Step 4: Download the utility (Note: I don’t know if WD supports the wget command. If not, write back and we’ll download a different way).

wget -O UserCredentialReset.sh https://github.com/ChuckPa/UserCredentialReset/releases/latest/download/UserCredentialReset.sh

Step 5: Make the script executable (you’ll need the admin password): sudo chmod +x UserCredentialReset.sh

Step 6: Run it: sudo ./UserCredentialReset.sh

Step 7: When prompted, enter the code from https://plex.tv/claim.

If it works, you’ll see “Claim completed without errors.”

Step 8: Start Plex Media Server and see if you can login and reach server settings.


Here's an example running on Ubuntu:
$ sudo ./UserCredentialReset.sh

          Plex Media Server user credential reset and reclaim tool (Ubuntu 24.04.3 LTS)

This utility will reset the server's credentials.
It will next reclaim the server for you using a Plex Claim token you provide from https://plex.tv/claim

Please enter Plex Claim Token copied from http://plex.tv/claim : claim-nottherealtoken

I just confirmed it running on PR4100

As long as the file is on the WD,
-and-
You SSH into it
-and-
Run it there, it works.

I put the file in where Plex is stored
/mnt/HD/HD_a2/Nas_Prog/plex_conf/Plex Media Server

You can put it in any media folder you want and have access to

root@WD-PR4100 Plex Media Server # cp Preferences.xml Preferences.xml-qa
root@WD-PR4100 Plex Media Server # ./UCR.sh 
./UCR.sh: line 206: whoami: not found

Thank You for your help. This solved my issue. It work with me unziping the file to my public folder and following the steps to navigate to the fold within command prompt and executing it. Thank you!!

Hi Chuck, I’ve managed to get into the root folder of my PR4100 and downloaded the zip file for the utility, would you able to provide some more detailed pointers of where to go from here.

I’ve manged to get to root@MyCloudPR4100 ~ #, just struggling from here on.

Think I’ve sorted it, many thanks for taking the time to post a solution!
