The game Fallout 4 has a companion app for Android that displays in-game info, and will interact with the PC game from your phone. IF I disable the Avast firewall, it works just fine. But with the firewall enabled the app cannot find my PC on the network.
I have enabled every setting I can find, giving Fallout 4 permission for both incoming and outgoing traffic.
What do I need to change to get the app through the firewall?
