PC Connect issues. I'm not a tech, it appears to be a conflict with Windows Firewall. Very frustrating, I have not use the Roon service in a few weeks and as I return unable to play music with guests arriving. Any help appreciated.

Sorry to hear about the ongoing issues. 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.
