This is what I am now stuck on when I log back in. Stuck on trying to connect to the laptop/PC and won’t let me get out of it
You should not connect to the PC since you don’t want to use this as your Roon Server. This is why I asked you to click on Oops, I meant to run as remote control.
It isn’t necessary to connect to the Roon apps on the PC when using the Roon GUI. Every time you do this, you are disconnecting from the Nucleus.
When you see the Connect to your Roon Server screen, use Configure Roon OS devices, and select the Nucleus. Then log in using your credentials (this will open a web page in your browser.)
I understand that, but when I log in I am greeted with “Connect to your Roon Server” and if I click on “Find my Roon Server” it keeps looking but cannot locate the Nucleus.
Then when I select on “Configure Roon OS devices” I click and I select the Nucleus at its IP address, click “save” and it still cannot see it.
Screenshots in order of occurence
Powered down everything on the network; modem, switch, Nucleus…everything.
After everything powered back up, same results still remain.
Roon cannot see a server, so I cannot log in, cannot do anything
I am at a loss as to what to do. Nothing in the connectivity changed as far as I can see from the last time I was able to use it to the current state it is now in.
Hey @gregnettles62,
Thank you for all the testing and screenshots, that’s exactly what we needed. This is a network puzzle, not a you problem.
Good news first: your Nucleus is completely healthy. The HDMI status screen and the web interface at
http://192.168.68.63
both confirm RoonOS is running, Roon Server is up (build 1658), and your database is intact. Nothing on the Nucleus is broken and none of your playlists or history are at risk. (My earlier .69 was a typo on my part, .63 is correct. Thanks to @mjw for catching that.)
So the problem is narrower than it feels: the Nucleus is fine, but the Roon app on your PC can’t finish connecting to it, even when you point it straight at the IP. Because you can load the web page at that same IP from that same PC, we know the two machines reach each other, which means something is blocking Roon specifically. Two things cause this almost every time:
- Windows Firewall. You reinstalled the Roon app recently, and Windows very often blocks the fresh copy. Please temporarily turn off Windows Defender Firewall (Settings → Privacy & security → Windows Security → Firewall & network protection), then reopen Roon and use Configure Roon OS devices → select the Nucleus. If it connects, we'll set a permanent exception so you can turn the firewall back on.
- App version. Your Nucleus is on Roon Server build 1658. If the PC app is older, it won't connect. Please grab the current app fresh from roonlabs.com/downloads and reinstall.
- Your DNS server (192.168.0.1) is on a different range than your gateway (192.168.68.1), and the netmask is unusual. That usually means both your Hytron modem and your TP-Link Deco are handing out addresses (a "double router" setup). It's not blocking you today, but it can make Roon's discovery flaky, so worth tidying up later.
- After any reboot of the Nucleus, give it a few minutes before testing, it needs a moment to come fully online.
We’ll get you back on the Nucleus. 
Thank you, Benjamin!
Here is what I have done and where I am at:
Turned off Windows Defender Firewall as you requested.
I then downloaded the newest app for Windows 11 from Roon as you requested.
I rebooted the Nucleus from the Configure OS Devices when I pointed at 192.168.68.63
(When I go to that IP address, select “Save” and press “Done” isn’t that how to select it as your
server? Or is there a step I am missing?)
When I launched the app, it initially gave me the choice of switching to the laptop as server, or
staying connected to the Nucleus. However, it also stated that I needed to
purchase additional licenses, but only the Nucleus initially showed up with the PC as options.
(I did have two PC’s at one point in time as servers before I got the Nucleus but disconnected
the older unit). Now only “This PC” shows up as an option as a server.
I can point directly at the Nucleus IP address, but the Roon app is still not seeing it.
If I go ahead and connect to the laptop (see image) and then go into “Settings>General” and
disconnect it, relaunch the app it goes to the same thing and connect to “This PC” is the only
choice I now have. (Sidenote: when it first launched, I saw both PC and Nucleus flash as
server choices for a millisecond and then lands on “This PC” as the only server option"
The somewhat good news is that if, I wanted to, I could at least use the PC for the time being but
obviously as you can tell from my efforts, it’s not what I want.
Please see attached screenshots, including my laptop/PC’s IP address as requested.
Sorry for the novel, but I want to provide as much detail as possible.
Thank you very much for the help!
I have done more verifying and testing and can only conclude that network is not the issue. It has been five days since I last responded to the tasks requested and have heard nothing back.
Did you resolve this issue?
Hi Geoff,
I am working on trying to resolve this now.
The Hytron modem is in fact found at 192.168.0.1 and the TP Link is in fact found at 192.168.68.1.
About as far as I can get without the fear of completely screwing something up!
Thanks for your help!
Greg
And yes, we did address this by running everything of a friends router who came to help and it and the gateway were on the same address and it did not change anything. Still could not get app to connect to the server.
Hi @gregnettles62,
Thanks for the screenshots and the update. Even if the addresses can be the same, it still needs to be one subnet, and the easiest way to get there is to enable Bridge Mode on the modem so it is not handing out IP addresses at all, then route everything through the Deco setup, your ISP can often do this remotely.
You also mentioned that you already tried running everything through a friend’s router, with the gateway and the rest of the network on the same address, and it still would not let the app connect to the server. That tells us the address alone was not the issue. Please keep us posted after the network is fully routed through the Deco setup, and we can take it from there.
So I have tried EVERYTHING that has been suggested, had three different people over to my home who are much more experienced and educated in networking issues, two of which work in their company’s IT teams and still to no avail cannot get Roon app to see the Roon Nucleus server. Everything is and has been running off my TP Link (Deco)
The ONLY other thing that I can think of is that I believe the last time I was able to use my Roon system was before an update was done (not positive but fairly certain as it was some time ago). At this point in time I am flushing money down the drain each month since I am paying monthly for something I cannot use and frankly I find this type of vendor support to be frustrating.
