Figured it out on my own. You can close this request.

Thanks @tom80H

To be clear - this :index_pointing_up: thread link above is in regards to the “core component” issue.

Claiming a server on Unraid can be a”fun” exercise in and of itself that I walked through on my own setup recently. Assuming Docker on Unraid, you can use a container variable of PLEX_CLAIM and put in a token that you can generate from https://plex.tv/claim

However, the method that I ended up using I found in this thread and consists of:

  • the issue being that claiming needs to occur using localhost:32400 (not from server_ip_address:32400)
  • from another device you can run ssh -L 32400:localhost:32400 root@server_ip_address (replace your server_ip_address with whatever you are using here)
  • after running that you should be able to then hit localhost:32400/web in your browser and claim the server

I would also note that YMMV and you may need a bit more work depending on how you have your Docker networking set up on your own system. I ended up switching my networking for the container over to “host” mode and then use the ip_address of the unraid server for these instructions to work before switching it back to my preferred setup once it was done.
