Description Of Issue
The Roon app is no longer seeing and communicating with the Core…
Hi @Andrew_Gear1,
Is the macOS device you shared a screenshot of above the Core machine or the remote?
Is your Core machine connected to the network via WiFi as well as the remotes?
That’s a snapshot of the core machine. It’s connected via wireless. I did use Fing to document the fact that it was seen on the network
Hi @Andrew_Gear1,
What kind of Roon Remotes are you trying to control the Core with? Is Roon + RAATServer still added as exceptions to your OSX firewall and any application firewalls you may have (McAFee/Bullguard/Little Snitch/ect.)? You can use these instructions to check the Apple firewall.
just an iPhone with the Roon app
Firewall not on…
Hi @Andrew_Gear1,
Did anything change in between when Roon was able to see the Core vs now? Any updates to router software or such?
You mentioned you used Fing and you were able to see the iPhone, can you confirm if the iPhone had the same IP address subnet as the Core (all numbers were the same except the last 3)?
If you have any multicast options on the router, can you confirm they have been turned on?
Subnet is the same. No updates to the router. It’s very strange. Was working like a charm
Hi @Andrew_Gear1,
Do you by any chance have another PC which you can try installing Roon on? When prompted on the “Choose your Core” screen, can you select the existing MacOS Core and connect properly to it? I wonder if this behavior only affects the iPhone, it will be a good data point to have.
