I have trouble updating my Nucleus One to the latest Roon Server version
Router > Network Switch > Nucleus One
Hey @Nicholas_Chan1,
Thanks for sharing your report!
Can you provide more details around your network switch? If you temporarily bypass it, are you able to update properly?
If you haven’t yet, I’d also safely stop Roon Server, then reboot both your router and Nucleus, and see if you have the same issue.
If you still have issues, see if you’re able to access the webUI of your Nucleus and perform an OS reinstall - that should help update to the latest build:
We’re not seeing any Nucleus tied to your account, so we’re unable to enable diagnostic mode - Can you please use the directions found here and send over a set of logs to our File Uploader? Once logs have been uploaded, please let us know so that we can check the server for your files, thanks!
Thanks for the suggestions.
My network setup is quite simple: I have a modem from my ISP connected to a router. From the router, a LAN cable connects to a Gigabit LAN switch. From the switch, one connection goes to my streamer DAC, and another goes to my Nucleus One—that’s the entire setup. For my computer, I’ve connected it directly to the router via LAN, as I didn’t want to pollute the signal path for my HiFi equipment by routing everything through the same switch.
I’ve already tried bypassing the switch and connecting the Nucleus directly to the router, but unfortunately, the update still fails. I’ve also safely stopped the Roon Server and rebooted both the router and the Nucleus, but the issue persists.
I’ve uploaded a set of log files through the File Uploader—hopefully that helps in diagnosing the issue. However, I encountered a problem where the RoonServer_log.txt file consistently fails to upload, and I’m not sure why.
Lastly, I understand from your message that my Nucleus One isn’t currently showing as tied to my account. Could you please advise how I can verify or correct that?
Appreciate your help and looking forward to your guidance on the next steps.
After doing some research on the Roon Community, I saw suggestions around entering a DNS server address. I just tried setting my DNS to 1.0.0.1, and after that change, I was able to successfully update the software on my Nucleus One.
Could you please confirm if this is considered a proper fix? Also, are you now able to see my account correctly associated with the Nucleus One on your end?
Appreciate your help as always.
Hi @Nicholas_Chan1,
I’m glad changing the DNS got things working for you.
Yes it is something we will often recommend to users. SO this should be fine.
Unfortunately we are still only seeing the zenmini server in your account.
Thanks for the update. The ZenMini you’re seeing is located at my other residence.
Is there anything else I can try to get the Nucleus One properly linked to my account? If there’s nothing more that can be done, are there any potential downsides to it not being connected to my account?
Appreciate your help!
Hey @Nicholas_Chan1,
The only downside would be that we couldn’t auto enable diagnostics mode to the Nuclues on our end - in which case you can always share manual Nucleus logs, which you’ve done above.
Happy listening!
