Solution: Configure TCP as well as the Port Settings of your Firewall
Configuring TCP and port settings in a firewall is necessary when you want to allow specific network traffic to pass through the firewall to reach a particular service or application running on a computer or server.
Before you can configure the firewall, you need to know which application or service requires access through the firewall and the specific port(s) it uses.
Click on "Advanced settings" on the left pane to open the Windows Firewall with the Advanced Security window.
In the Windows Firewall with Advanced Security window, right-click "Inbound Rules" on the left pane and select "New Rule."
Select "TCP" and specify the port number(s) required by the application. If the application uses multiple ports, create a rule for each port.
Choose "Allow the connection" and click "Next."
Specify when the rule applies (usually leave the defaults) and give the rule a name. Click "Finish."
