Description of Issue

Without any warning or any cause, my Roon Nucleus+ stopped being seen in my Windows10 network. I’ve tried every single idea mentioned on these Roon forums. I’ve checked SMB sharing, etc. I fear that the Nucleus+ internal SSD has failed. If that’s the case, then I’ve also lost the Roon Settings Backups that I foolishly backed-up to that internal SSD. I am so, so ,so frustrated. Any help will be so appreciated.

Hook up a monitor at boot time and take note of the resulting messages.

A major no-no, but there’s little that can be done about that, now.

One additional thing to point out… The Nucleus+ powers on based on the light near the power switch. And also, the green light next to the cat5 connector blinks green as well.

Do either of those lights help my cause?

Not really. You need to hook up a monitor. I take it you can’t get on the Web GUI?

Do you mean the M.2 drive that the OS is on, or do you mean a 2nd internal drive, where one might keep music files, e.g.? If you mean a 2nd drive, then that is probably still intact.

One thing you could try is shut down your Nucleus, unplug the power supply, wait a few minutes, then try again. That sometimes works.

I set the scheduled Roon Settings Backups to locate on the 2nd drive where my music is also living (hopefully).

Correct, I cannot get to the Web GUI. This happened once before a few years ago. I just do not remember exactly how it resolved itself.

Excellent point. It might be the M.2 drive that has failed. I guess that’s a better situation?

Well, your Backup, not to mention your music files, are probably still okay

What does your monitor say when you boot the Nucleus?

Instead of flailing around further, that’s the next step.

Don’t backup to your Roon music “watched” folder/drive. Use a separate HDD plugged into your Nucleus for backups.

Allow me to figure out how best to attach a monitor directly to the Nucleus. Agreed that is my next required step.

Silly question, what port do I use to connect a monitor directly to the Nucleus? Thanks.

Shouldn’t matter, but if one HDMI port doesn’t give a display, try the other.

The HDMI port…

Some very, very good (yet slightly embarrassing) news to report … My second SSD is actually an external 8TB SSD (it’s been so long since I’ve looked that I’d forgotten). Unplugged it and then plugged it into a laptop – it works fine! My Roon Backups are located there along with all of my personal music collection. So that is great. Thank you so much for leading me to this point.

Still, this leaves the Nucleus+ as a non-working actor. Next step, I will hook up a monitor directly to the unit. I will report my findings shortly.

Plugged Nucleus+ into monitor using HDMI port. Started up the Nucleus. Absolutely nothing on the monitor at all. Zilch.

Ok, there were two ways to go.

If you got a display with message complaining about not finding an OS or something to that effect, then I would say that your M.2 had died. Something relatively easy to fix.

Not getting any display probably means that your motherboard or a major component has died. Which is much worse, of course.

Where did you buy it and is the 2 year warrant still in effect are the next questions, but that’s something for @support to address.

since nothing at all on the monitor, then looks like motherboard, etc has gone kaput. purchased from an authorized Roon dealer but way out of warranty. am I out of luck? when will Roon Support team comment on this thread?

I would say yes.

They’re always pretty busy, but I tagged them so they might respond quicker.

Don’t know what your skill set is, but if the Nucleus is a loss it will probably be cheaper for you to buy a NUC and put ROCK on it, rather than have the Nucleus fixed out of warranty.

If you still have warranty for it, you can go through the RMA process via the dealer.

If the 2-year warranty has already expired, power down the Nucleus. Disconnect the m.2 boot SSD, and tell me the model and capacity of your m.2 boot SSD (or post a photo). Then power it on without the m.2 SSD, see if anything shows on the HDMI monitor. If yes, then the m.2 boot SSD has failed - in that case you can purchase the smallest capacity version of Samsung 970 m.2 SSD as the replacement boot SSD, install ROCK first, then ask support to turn it back to Nucleus firmware by providing serial number and proof of purchase.

Is the monitor setup for the HDMI intput?

Incorrect input setting will also display nothing upon bootup.

Good morning – And thank you all for the help. And Merry Christmas.

My office desktop computer monitor is connected via HDMI cable so I think my test connection to the Nucleus was valid. Next step for me is to check the Nucleus box without the m.2 SSD installed. I will report back later today with that result.

As a side comment, I am really quite surprised that no one from Roon Support has jumped onto this thread? Buying a Nucleus should include some level of support from the Roon team. There’s no phone number to call that I can find so this forum is it, no?
