PR4100 Plex app configure error "Not Authorised"

After installing the Plex Media Server on My Cloud Dashboard, I have tried configuring the app and get an error that I cannot resolve. The error reads “Not Authorised - you do not have access to this server”. Can anyone help me with this issue? I tried looking for a previous post but cannot the same issue.
Any help much appreciated!

Hi @G3GMW,

Have you opened a Support Case? If not opened, for more information, please contact the WD Technical Support team for the best assistance and troubleshooting:

Have you ever been able to resolve your issue? It has been a while since I set up my Plex. But it works fine, I don’t seem to have any issues. As I recall you need to have your Plex account fully set up. Additionally, you need to pay for the Plex Pass in order to set up your PR4100. I paid the lifetime fee. Totally worth it. I don’t pay for any streaming service.

I ran Plex on my PR4100 for nearly a year before buying Plex pass, hopefully that hasn’t changed and is now a requirement!

I fix the (recently very regular) problem of “Not Authorized” errors using a script from here: GitHub - uglymagoo/plex-claim-server.

Copy this to a share on the NAS.

To use it, you’ll need to ssh to the NAS and navigate to the directory it’s in, it’ll be something like /mnt/HD/HD_a2/your_share_name/

Before running the script, on my PR4100 I set the environment variable like this:

export PLEX_MEDIA_SERVER_APPLICATION_SUPPORT_DIR=‘/mnt/HD/HD_a2/Nas_Prog/plex_conf’

Then run the script like this:

sudo ./plex-claim-server.sh “YOUR_CLAIM_CODE”

Replacing YOUR_CLAIM_CODE with the code from Claim | Plex - remember to keep the quotes when you run the command.

Once the Plex app is restarted (using the PR4100 control panel), reload the Plex client and it should be fixed.
