Description of Issue

I can no longer find the Roon core when I look for it on my iPad running the Roon remote
I can see the NUC on my network.

I have been running the NUC headless but for some reason it stopped being seen by the Remote. I am also having issues with the SoTM but that is common and I need to finally get rid of it after years of poor function.

Hello @Jerry_Sobel ,

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.

Is it possible to temporarily also disable the firewall router? Is there any change in behavior if you do so? Let us know when possible, thanks!
