Ipad can not locate the Roon core. Tried with both firewall on and off, Proton VPN on and off and any combination of before mentioned. Confirmed IP and Subnet are the same. CPU and Lumin P1 are connect via ethernet switch, ipad wifi.
Toggle IGMP setting (and any multicast setting) in Verizon router then reboot everything
If that still does not work, consider adding a WiFi access point behind the switch, then connect the Roon Core and Lumin to Ethernet ports of the access point, and turn off WiFi from the router
I have uninstalled proton VPN and GeForce experience, toggled IGMP settings, rebooted everything and turned firewalls of and every possible variation of the above to no avail.
Funny thing is, when i turn my VPN on or off, the remote actually finds the Roon core for a period of 10 seconds, but never connects to it and cant locate after???
I know you mentioned checking the firewall, but to be explicit on what settings to check:
Since you are using a Windows PC, I would verify that both Roon.exe and RAATServer.exe have been added as exceptions to your Windows firewall.
You can use these instructions to add the exceptions and the executables themselves would be located in your Database Location/Application folder path.
I would also add these exceptions to any Antivirus or other Firewall blocking applications you may have and ensure that you connected to your network via a Private network, not a Public one, see this guide for more information.
I’ve also enabled logging for your Roon Core, so if you can get it back online even for a few seconds and let me know, I can check your logs for clues.
I am seeing some issues with RAATServer starting properly, I wonder if this could be related. I suggest generating a new RAATServer instance. You can generate a new RAATServer instance on your device by following these instructions, but please be aware that this will reset your Roon Settings → Audio Tab to factory settings and I would advise making a backup of any custom DSP settings you have:
