Mismatch of IP Address between Windows Roon Software and iPad after Titan Server Installation (ref#AKMBWY)

What’s happening?

· I'm having trouble connecting to Roon

What type of connection issue?

· Something else

Describe the issue

After installing new Titan server, my Windows Roon Software has a different ip address than I see from my iPad. How can I reset the Windows ip address shown for the Titan to match?

Describe your network setup

Cat 6 Ethernet network

(I removed your email address from the screenshot - it’s not a good idea to post private email addresses on a public forum)

I assume that what you are seeing in the screenshot is your old Nucleus - not the Titan, so simply click the Disconnect button in this screen to display the Roon Server devices currently active in your network. You should see the Titan and be able to connect to it.

Geoff, you may be correct about this being the ip address for my old Nucleus. I have no way to verify as I did the backup and disconnected per the checklist I saw on the Roon community posts.

My Mac devices all find the new Titan without difficulty. Unfortunately, my file library is on my Windows 11 system. I am trying to import my saved files to my new internal drive.

I uninstalled Roon in Windows 11 trying to get past this issue. On reinstalling Roon on the PC, it recognizes only the Roon Titan, but with an incorrect address.

Just for grins, have changed cables and installed a new switch. The Nucleus Titan appears as the only Roon OS device with an ip address of 192.168.1.153. The correct ip address for the Titan is 192.168.68.61.

Is there a way to do an override of the ip address?

Where are you seeing this? Can you post a screenshot of this?

Can you describe your network setup in detail? Is it possible that you have two subnets?

Hi @Cary_Wigington,
Are you still having trouble with your Titan? If you are please post the screenshots @Geoff_Coupe mentioned.

Per the earlier request, I have determined my desktop Windows 11 computer has the following IP address; 192.168.1.80.

My Titan address is 192.168.68.61. Both are using the same router, and are part of the same cat 6 network off the same switch.

I am questioning whether the Titan is using the wireless network with my home, or does it default to ethernet when the cable is connected. I don’t find a menu setting for choosing wired vs. wireless.

Thoughts?

From this, it sounds as though the Titan has somehow been set up with a static address. You may need to reset its network address:

Well, the fun and games continue. I reset the Titan ip address per the instructions. My PC now sees the Titan address as 192.168.1.153, but won’t connect.

My Apple devices still show the ip address as 192.168.68.61. The system works fine using my Apple iPads and MacBook.

Over the course of multiple days I moved my music on to the new internal ssd of the Titan. I could have done this in a hour or so using my PC and Ethernet network.

I have power cycled the server and PC. I have uninstalled and reinstalled the Roon software.

My Nucleus ran flawlessly for 3 years using this network. The only variable is the new Titan.

Thoughts?

So the Titan is on the same subnet (192.168.1.xxx) as your PC, but your Apple iPads and MacBook seem to be on a completely different one (192.168.68.xxx).

Do you still have your old Nucleus in operation? If so, then I think it has the 192.168.68.61 address and is the Roon Server that your iPads and MacBook are still using.

First, can you say more about what you see when you say that your PC “won’t connect” with your Titan? They are both in the same subnet, so Roon on the PC should come up with a screen showing that the Titan is ready to be connected to and show a “Connect” button.

Second - you need to have all devices on the one subnet (192.168.1.xxx) - I don’t know why you have apparently got two subnets while you originally had one, but something seems to have changed in your network setup (recently?).

Geoff, I am fairly sure the Mac devices are not connecting to the old Nucleus. I took advantage of the recent trade in offer and sent it back by UPS last week.

For grins, I installed Roon on my old office computer. It is a Windows 10 system. My current system is Windows 11.

The new installation found the Titan at the same ip address on the correct subnet, but fails to connect as well.

I have successfully used Roon from my Windows 11 computer for about three years. The only change to the network is swapping the Titan for my Nucleus.

I have no explanation for why the Windows computers see the Titan on the same subnet as the Titan, and Apple devices effortlessly detect and connect to the Titan using a different subnet. This is not of my doing.

I have turned off my firewall while trying to connect. I have checked the advanced settings to make the option to detect and connect to other devices is on.

I have disconnected my iPad to see if it would reconnect on the current subnet showing on the Windows computers. It connects, but on the other subnet.

I am stumped. What was expected to take a couple of hours has consumed most of ten days.

So it seems to me that the first thing to get sorted is to have just one subnet, not two. As the Help article on subnets states:

Roon requires all devices to be on the same IP range , so any devices used by Roon can’t be on a different subnet than the device running Roon Server. This includes remotes and endpoints.

Geoff, the Windows computers show the Titan ip address that is on the same subnet as the Windows compiuters. The Apple computers display and connect to an address on a different subnet.

As previously requested, I did reset the ip address of the Titan to get the Titan on the same subnet as the Windows computers.

After the reset, the Windows computers see, but don’t connect to the Titan. Disconnecting the Apple products doesn’t appear to help.

Looking back through your replies, I see now that the Titan was always getting a good address - I had suggested doing a “reset network” on it before it became clear that you are running two subnets.

I had asked earlier:

First, can you say more about what you see when you say that your PC “won’t connect” with your Titan? They are both in the same subnet, so Roon on the PC should come up with a screen showing that the Titan is ready to be connected to and show a “Connect” button.

And further - I suspect that all your problems will go away once you have everything in a single subnet… You really should look to do this.

Hi @Cary_Wigington,
I agree with @Geoff_Coupe here. Getting everything on the same subnet will most likely fix your issues here. If you need any help doing that please let us know.

Well, I finally found a workaround. I turned off all of my Apple devices and removed power from my Wi-Fi mesh devices. I shut down my PC and the Titan. After restarting the Titan, I started the PC. It connected instantly.

I powered on my Wi-Fi mesh system. Upon restarting my iPhone, it connected with the correct ip address. One of my iPads struggled a bit. I deleted the Roon app and reinstalled it. The iPad connected instantly.

I have no idea why the Apple products chose an ip address different than I was seeing on my Windows desktops.

Anyhow, I appreciate your help.

The success was fleeting. As soon as I restarted my wireless network and connected via Apple devices, I am seeing different ip addresses with different subnets.

The Window computer can no longer connect.

@Cary_Wigington do you have iCloud Private Relay activated on your Apple devices?

That is a good question. In settings, private relay is turned on (apparently the default setting), however there is a note below my wireless network doesn’t support this feature or is turned off in the wireless settings.
