Describe the issue

Unable to UNAUTHORIZE existing Roon Core to setup new Nucleus One

Are you still connecting to the old Nucleus per chance? It looks like your license was already transferred to the Nucleus One:

Now I’m getting a message that says, “Are you online?” but the same net effect – unable to unauthorize existing MEDIASERVER6630.

Sorry, I posted the wrong screenshot to the initial message. Here is what it shows when I try to run Roon Core on the Nucleus One:

Clicking Unauthorize briefly shows the message “Deauthorizing…” followed by “Refreshing…” but it never leaves this screen.

I have an existing Roon Core running on a very powerful Windows 11 mini PC (Core i9, 32GB RAM, 1TB SSD) and it has been virtually unusable. So, I purchased a Nucleus One to replace it. I can see the Nucleus One on the network but when I login it tells me I need to “Unauthorize” the existing device (called MEDIASERVER6630). I click the “Unauthorize” button over and over but it does nothing. When I attempt to do the same thing on the existing device (MEDIASERVER6630), it shows that I am logged in to “Nucleus One” and gives me the same “Unauthorize” option. That DOES work and I am able to load Roon on the old server.

How can I unauthorize the old server so I can set up the new one?

Many thanks.

Ok that’s weird. No idea, sorry. One for official support, I guess

No worries, I appreciate you trying to help!

Hi @James_Feck,

Very sorry for the delay in responding here. Thank you for your patience.

First off, our diagnostic servers seem to show that your Nucleus One had an active session since you last posted here. Forgive me if you’ve already resolved this behind the scenes and this post is now redundant.

If you’re still having trouble, you can follow these steps to fully erase the Roon Server instance on the PC now that you’ve migrated. Only take these steps if you have a reliable Backup.

  • Exit out of RoonServer on the PC
  • Navigate to your RoonServer’s Database Location
  • Find the folder that says “RoonServer” and delete it. Don’t delete the folder named “Roon’ since that houses the GUI (Roon).

Let us know if this helps. Thank you!

So, I stumbled upon the solution to this issue and thought I’d post here in case others have the problem in the future. I can’t explain it exactly, but the issue seems NOT to have been between the two Roon Cores but rather with the profoundly unhelpful “Are you online?” error. I run Tailscale on my network and that was apparently causing issues.

I figured this out when I navigated to the Web Administration page on the Nucleus One and noticed the Reinstall Operating System button. I figured I would try this in the hope that installing the latest OS might help. At the time, there was NO Tailscale option available on the page.

After installing the latest OS version, the Tailscale section appeared. I added the Nucleus One to my Tailnet and boom – the Nucleus One connected properly and I was able to move my license to the new device.

Early testing shows the Roon device to be infinitely more stable and reliable than the mini PC I had been using. This still makes no sense to me, but it is what it is. I’ll happily send that $1100 box back to Amazon and use the $600 Nucleus One.

Hope this helps someone in the future!
