X-plane fails to connect to GMapHD using FSWidgets plugin for X-plane. The connection works when I disable Avast firewall. Reconnecting the firewall I note it has blocked System32\svchost.exe.
The rules are set to allow this app, (System32\svchost.exe) to access the internet in/out, the app. is being blocked coming in. I have reloaded the FSwidgets plugin and GMapHD, to no avail, System32\svchost.exe is still being blocked. Would very much appreciate a resolution.
Is your firewall network profile in puplic or private mode?
Try change … you may need to reboot after

=========================================================
NOTE:The Network profiles control the settings which determine how strictly Firewall protects your PC.
Private: a lower level of security suitable for when your PC is connected to a trusted network such as your home or work network. This profile enables better connectivity, and permits all communication within the network.
Public: a higher level of security suitable for when your PC is connected to a public network such as in a cafe or airport. Because public networks present greater security risks, no incoming communication is permitted when this profile is set.
As easy as that… thank you very much.
Should I leave it here?
