iPhone unable to find Nucleus server (ref#I4R3Q7)

Is Roon Server running?

· Yes, Roon Server is turned on and running.

What do you see on your screen?

· "Looking for your Roon Server"

Please try to restart your Roon Server by closing the Roon app in the taskbar or rebooting your Roon Server machine.

· No, the issue remains the same

Please try to restart your network setup by unplugging, waiting 30 seconds and then replugging in your networking gear.

· No, the issue remains the same

Please select how you've connected your Roon Server to the internet

· Roon Server is connected by *Ethernet*

Have you checked your firewall settings to ensure that Roon is allowed through?

· Roon still won't connect even after checking this aspect

Have you verified that Roon Server is on the same subnet as your Remotes?

· My Remotes and Server are on the same subnet and I still can't connect

Sometimes the issues can be resolved with a reinstall of your Roon Remote app. Let's try to perform a reinstall and see if it helps.

· I've reinstalled the Roon Remote but it did not help

What is the operating system of your Roon Server host machine?

· *Nucleus*

Select any of the following components that are present in your local network setup

· *Mesh networks*

You mentioned a mesh network in your setup. Certain common mesh networks might require slight reconfiguration to support Roon.

· None of the above

Describe the issue

Describe your network setup

Hey @david4,

Thanks for writing in, and welcome to the community! We’re excited to have you here, and apologize in that it’s an issue that prompted your initial post.

I see you mention that your devices all fall within the same subnet, but sometimes having mesh networks can distort this a bit. If you temporarily disable your other mesh nodes, and force a connection to your primary router from your iPhone, are you able to connect?

I see you’ve also attempted a fresh install of Roon on the iOS device as well - and while your iPads seem to connect normally, it may be worth testing out disabling your Mac firewall on your server temporarily. Here’s more info on firewall exceptions for Roon:

We’ll be on standby for your reply! :raised_hands:

you wrote about “disabling your Mac firewall on your server temporarily.”. I am running a nucleus one, so I am not sure that I understand the relevance of this. I still cannot get the iPhone to see the nucleus one.

I have followed all of your advice and no luck. if I do reboot the Roon nucleus one the iPhone does now recognize the ip address and try to connect, but it never moves beyond this point (see screenshot - attached).

Hi @david4,

Thank you for your post. Did you formerly host RoonServer on a MacOS machine? Our diagnostics servers show that there’s a second active RoonServer associated with your account.

If you did migrate to the Nucleus One recently, how precisely did you perform the migration?

Please share a screenshot of the Nucleus Web Administration page - this should have some diagnostic information about the network configuration.

Do you have any additional network components in this topology, like mesh nodes, managed switches, or second subnets? You mentioned mesh nodes in your description. Where is the Nucleus One relative to the main router? Please describe the full network pathway involved.

The AX3 router should have an option to disable IPv6 - try toggling this off temporarily to see if it has any effect. Make sure multicast forwarding and IGMP snooping are enabled in any mesh router settings, as well. These are essential for remote discovery and are often intertwined settings in the router firmware, even in a single VLAN setup.

Thank you!

1.) I did not “migrate”. I performed a fresh install on the Roon nucleus one. When I did so, I used 2 freshly formatted SSDs connected via USB. The music was copied directly to those disks from my personal music archives. No databases or other configuration aspects were moved over.

2.) Yes, I did host Roon server on mac but I was unable to figure out how to properly uninstall all of its associated files/components (unfortunately, there is no uninstaller nor could I find any decent instructions on the web about how to do this).

I was able to finally solve the problem yesterday by doing the following:

(A.) I re- indexed my Mac and all of its associated disks.
(B.). I then preformed a search and deleted any and all files with any reference to “Roon” in their titles/designations.
(C.) I rebooted the computer and reinstalled Roon (without the Roon Server).

The problem has now been solved. It might be helpful to other Roon users if Roon would consider providing a detailed FAQ/ Instructions on how to properly delete Roon software from Mac.

Thank you.

Hi @david4,
Thanks for the update—we’re glad to hear you were able to resolve the issue!

For future reference, you can fully remove Roon from a Mac by deleting the Roon and RoonServer folders located in the ~/Library directory. To access this, open Finder, press Command + Shift + G, and enter ~/Library. From there, you can locate and remove those folders.

We appreciate your feedback on providing clearer uninstall instructions, and we’ll take that into consideration. Let us know if there’s anything else we can help with!
