· I really need help. I've wasted well over 20 hours trying to get the nucleus one to work. I'm trying to transfer my files over from my seagate HD, but Roon takes well over 5 min to connect to the server, stays connected for about 1-2 minutes and then freezes and tells me "Uh-oh...". I'm not tech savvy. I asked a question in the forum and got a canned typical IT response. I don't work with computers this way, and I didn't think I needed an advanced degree to understand how to plug and play. This is my last ditch effort before I return the nucleus and cancel my subscription. Thanks.
I’m running a Michi x3 series 2 integrated amp if that helps. I do have a lot of really great quality songs on my HD, not sure if that matters. I really - really want the nucleus to work, but I’m at my wits end in trying to get it to work. Fingers crossed you guys can help me resolve this so I don’t have to return it.
Hi @novakcination — I’m really sorry you’ve had to spend so much time on this. You don’t need to be “tech savvy” for Nucleus to work, and we’ll keep this in plain language.
With some Eero setups, your phone/computer can end up on a different “network group” (subnet) than the Nucleus. If they’re not on the same one, Roon can’t reliably find the server and you’ll see long connection times, freezes, and “Uh-oh”.
Do a quick reboot (in the right order)
Unplug Nucleus One power for 10 seconds, plug it back in
Reboot your Eero (use the Eero app → Restart)
Restart the device you use as a controller (your phone/iPad/computer)
Make sure everything is on the same Wi-Fi
On your phone/tablet/computer, connect to your main Eero Wi-Fi name (not a guest network).
If you have Guest Network enabled in Eero, please turn it off temporarily for this test.
]Check if you have more than one subnet (easy way)
On your phone/tablet/computer, open Wi-Fi details and look for IP address (it will look like 192.168.x.xxx).
Then tell us two things:
The IP address of your phone/tablet/computer (just the first 3 numbers are enough, like 192.168.4.x)
The IP address shown for Nucleus One inside the Eero app (Eero app → Devices → Nucleus)
If those first 3 numbers don’t match (example: phone is 192.168.4.x but Nucleus is 192.168.5.x), that explains the issue.
If possible, connect the Nucleus One by Ethernet cable directly to the main Eero/router (not a satellite node). This usually forces it onto the same network and stabilizes discovery.
Reply with:
Are you using iPhone/iPad, Mac, or Windows as your controller?
The two IP “prefixes” (like 192.168.4.x vs 192.168.5.x) for controller and Nucleus from Step 3
The IP address for phone: 192.168.4 / Eero "gateway Eero IP 192.168.4.1 / IPv6 Link-Local - fe80:0:0:0:4247:5eff:fea3:8c32/64
Nucleus - Here I have an IP address of 192.168.4.14 / I have an IPv6 address of fe80:0:0:03256:ff:fe18:6aa4
Thank you for your quick response as well as your assistance. I hope I provided enough detail to either resolve the issue or help better pin-point the issue. Please let me know if there’s anything I else I can provide / do.
I tried everything you wanted me and the issue still isn’t resolved; it still takes 5+ min to connect to the Roon server, I’m connected for 1-2 minutes and then the loading screen appears for a few minutes before I get the “uh-oh…” message. I can’t transfer my files nor listen to music. It’s stuck in this endless loop of frustration. Is there anything else that can be done to assist me in resolving this? Thanks,
W
Thanks for the additional information! It is not clear if you’ve set up a direct ethernet connection from your Nucleus directly to your primary router - is this something you can try?
Then, reboot both your Nucleus and router, and see how things perform.
Also, how specifically are you transferring your files? Are you dragging + dropping? Thank you!
My primary router is in another part of the home. I don’t have a direct connection to it and I can’t transfer my integrated amp out to that room. Is it possible to connect the nucleus to my primary router without the integrated amp / DAC? If so, I can definitely give that a go.
I’m transferring the files by following the prompts in Roon. Meaning I open the app and click on my HD and it transfers automatically. Is there a more efficient way to do this?
If I hook my Mac up to the nucleus, my files will transfer, but I don’t want to use my computer at all. I want to use my phone and / or iPad as the controller. Less wires and clutter…
I hooked up the nucleus one to my main eero router as advised. Both IP addresses are as follows:
IP address phone: 192.168.4.16
Nucleus one Eero: 192.168.4.26
My nucleus still performs the same; it starts transferring my tracks and then freezes and says’ “uh-oh”. It then goes back to loading and stating, “It’s waiting for my Roon server” for about 5 min and then starts the whole process over…
Thanks for the update — I want to clarify one important point based on what we can see from your Nucleus.
From diagnostics, your Seagate drive is already correctly mounted on the Nucleus and is actively in use.
The drive is ~54% full (about 7.8 TB used), which confirms that the Nucleus can see the disk and its contents without any issues.
Because of that, we want to better understand what you mean by “copying” or “transferring” files.
To help us move forward, could you please clarify:
Are the music files already on this Seagate drive, and you simply want Roon to use them?
Or are you trying to add new files from another device (for example, from a Mac or another external drive) onto the Seagate drive that’s connected to the Nucleus?
Right now, the disk itself is healthy and accessible, so the next step depends on what you’re actually trying to add or move, rather than a problem with the drive or the Nucleus.
Once we understand that part, we can give you the simplest and most reliable way forward.
If the nucleus itself if fine, then why am I not able to stay connected to it?
The nucleus also takes 3-7 minutes to load into the server.
Once I’m loaded in it only stays connected for 1-3 minutes before losing connection to the server. In other words, I can’t even stay connected to the nucleus, even when I’m connected directly to the main router.
I can’t even play music from Tidal, because I can’t stay connected. I ask because I don’t understand it.
You have 7.8TB of music files? Please, what is the size of your library - how many tracks do you have? A Nucleus One is designed to handle up to 100,000 tracks.
I’ll have to check later, but I do have over 100,000 tracks. I’m fortunate enough to have a lot of really great quality music. I also have several friends with the same music library, same seagate HD and they all use Roon nucleus’ with no issues connecting to the server.
Are you implying that I’m having these issues because I have too many tracks? If so, what is a solution? Do I need to pick and choose which files I want the nucleus to import? What is the best method to transfer the “chosen” files?
Roon can’t offer support in cases where the user is open about violating copyright law.
The Nucleus One is not designed to handle more than 100k tracks. If you share a screenshot of your web administration page, we can advise on whether or not this unit is experiencing RAM/processing issues as a result of the library size.
As for the steps we’ve recommended with Eero - the router firmware will often relegate devices to separate class-C blocks, which it treats functionally like separate subnets. Please see here:
We’re going to close this conversation, since you’ve openly admitted that you are sharing music illegally.
I was just messing with that guy. I don’t share the music I’ve bought. I’ve spent 30+ years purchasing all of my music. I have a really nice music set up and it’s my hobby. I’ve spent thousands on music and equipment throughout the years. My friends all have very large libraries and most of them have much larger libraries, and we all have very similar tastes. The only music I share is through my family plan on TIDAL. I’m thankful for Jim_F’s concern, and I’m sure his library is as legit as mine.
I have 7 albums in my library, all legal. Three of them are my brother, one of which I am the drummer. One album is my son’s ska band, the Del Rays. One was free from Qobuz and one I ripped from a DVD I bought, Beth Hart and Joe Bonamassa Live In Amsterdam. The last I made with 4 tracks I purchased on iTunes.
