To make your system more secure, Windows Firewall is active. Some apps might be blocked by the Windows Firewall. For your app to work properly, you might need to allow that app to receive information through the Windows Firewall.
-
In the Windows, search for and open Firewall and network protection.
-
Click Allow an app through Windows Firewall.
-
Click Change settings. You might be asked for an admin password or to confirm your choice.
-
Select the check box next to the app you want to allow, select the network types you want to allow communication on, and then click OK.
If the firewall is blocking the app and if the app is not in the list as described in the previous instructions, you might need to open a port, which is a way to receive information through the firewall. If you need to open a port to play an on-line game with friends, be aware the ports stay open all the time, so it is recommended to close the ports when you no longer need them open.
To open a port, use the following instructions.
-
In the Windows, search for and open Firewall and network protection.
-
Click Advanced settings. You might be asked for an admin password or to confirm your choice.
-
In the Windows Firewall with the Advanced Security dialog box open, in the left pane click Inbound Rules, and then in the right pane click New Rule.
-
Follow the on-screen instructions.
