I installed Roon on my Mac (Tahoe 26.4.1) desktop computer where my music files reside. I connected by cable to my Oppo 205. I was able to play thru the Oppo (of course with only the desktop controls active, and not really sure if I was getting the 192/24 resolution of the music I chose). I say this to demonstrate I have successfully installed Roon server.
On my desktop, I enabled permissions in all areas I could find (Privacy & Security>Local Network> Roon app and RoonServer.app /// Network>Firewall>Options>Allow Incoming Connections for RATTServer, RATTServer.app, Roon.app and RoonAppliance.app). I turned off (BitDefender) VPN and Shield. Note that Roon is not listed under Location Services.
On my iPad, I enabled permissions in all areas I could find (Privacy & Security>Local Network>Roon /// Apps>Roon>Local Network ON, Celluar Data ON, >Roon Settings> Reset Roon Remote on next Startup OFF and Save logs to Files on next startup OFF)
I opened Roon on my iPad but could not get past 'Looking for your Roon Server.' I tap help and entered my IP address, and it returns to 'Looking for your Roon Server.' My IP Address is Fixed.
Reason for Trying Roon: I have Qobuz, and even with the Oppo's Gapless Play enabled, it is still gapped. My goal with Roon is to stream Qobuz content with true gapless play, and also to integrate my personal .flac music collection with my Qobuz favorites. Will Roon do the first, actually stream Qobuz with true gapless play to the Oppo 205?
Tell us about your home network
· Router: XGS-1008 Luxul 8-Port Gigabit Switch, no switches or extenders, as previously stated, VPN off and BitDefender off too.
According to our diagnostic servers, the iPad might be on a separate subnetwork from the other devices running Roon on your network.
We don’t see the expected mDNS discovery announcements from the iPad in Roon Server logs, which usually means the router has restricted traffic from passing between subnetworks.
Yes, the IP addresses did not match the first 7 digits. But…
After checking using terminal.app, I changed to manual IP address entry and chose one not being used. I confirmed both ipad and desktop have the same subnet mask and router IP addresses. I turned off Private Wi-fi Address.
I still cannot connect my ipad to the roon server.
I’m 74 and mostly self-taught (but had computers since DOS4). I used Google AI to teach me how to get both computers on the same sub-network. Maybe I missed something?
I rebooted the router (did not help). I was on phone with Xfinity for over an hour. They say they do not block or restrict anything. I entered admin on my router. I found that the subnet mask on my desktop and ipad were not the same as on the router. Google said to change the deskop and ipad to match the router (changed 255.255.252.0 to 255.255.255.0). I confirmed both were successfully changed.
Roon remote on ipad is still stuck on “Looking for your Roon Server.”
Now that I have access to my router settings, what else can I check?
Well, things have gotten worse. After manually setting IP address, submask and router and after adjusting the router settings as described above (with no success getting the remote roon app to connect with the server), I changed my ipad IP settings from manual to auto. Previously, this left the router and submask the same and just changed the last number of the IP address.
This time, the IP address and router address changed itself to the router admin (10.0.0.1). Even after restoring an icloud backup from last week left these wrong numbers in place. Manually changing back to the correct values still was unable to connect to roon server.
What is even worse is that now, mConnect (thru Qobuz) cannot find my oppo 205. So I’m totally SOL for remote music. I’m having an expert come to my house ($$) to see if they can fix it. They are coming Tuesday (5/19) morning. If anyone has any suggestions, I’d love to hear them. I have an extra transportation charge now that they restricted their service area.
Thanks for the replies and additional information - I’m so sorry to hear you’re in such a tight spot currently. Here are some immediate findings from a fresh diagnostic report:
Problem 1: Your Mac has two active network interfaces on different subnets
These two interfaces are on different subnets. The Roon logs confirm this, Roon's local discovery protocol is advertising both IPs simultaneously (Adding User IP 192.168.4.55 and Adding User IP 192.168.4.56).
Your iPad is on Wi-Fi and may be trying to reach the Ethernet IP, or Roon is confused about which interface to use.
As an immediate next step - Disconnect one of the two network connections on your Mac.
Your Mac is simultaneously connected via both Wi-Fi and Ethernet. This is the most likely cause of the iPad failing to find the server. Roon gets confused when a server advertises two IPs on two different subnets.
Go to System Settings → Network and either:
Turn Wi-Fi off entirely (since your Oppo is connected via USB/Ethernet anyway), or
Unplug the Ethernet cable temporarily to test
Then open Roon on your iPad and see if it finds the server. If it does, you've confirmed the dual-interface problem.
Also check that your iPad is on the same network as your Mac. On the iPad: Settings → Wi-Fi → tap your network name → check the IP. It should be 192.168.4.x. If it shows anything starting with 10.x.x.x, something went wrong from your earlier manual IP changes, fix that by setting it back to Automatic (DHCP).
Lastly, in macOS System Settings → Network → Firewall → Options, confirm that RoonServer, not just Roon shows “Allow incoming connections.” The log shows RAAT connections occasionally getting refused, which can happen if only the parent Roon.app is listed but not the internal RoonServer process.
I hope this brings some stability back into your setup for some weekend listening
Just to clarify, turning off either wi-fi or Ethernet is a diagnostic procedure? Because I need both for Roon to work. The iPad communicates with the Roon server on the Mac via wi-fi, but the Mac communicates with the Oppo via the Ethernet.
SUCCESS! After spending 2.5 hours with google AI, it figured out my ipad was on the main network, while my mac and oppo were on the eero network. Simply turning on airplane mode, then off, while standing near the eero device, caused the ipad to be on the eero and it immediately connected to the mac.
I selected the oppo as the device, and at first audio played but not video. I made some network changes on the oppo, and now no audio either. Will work on it later and open a new thread if I can’t fix.
