1 - Open Windows Firewall
To find the firewall simply (on Windows 10 and Windows Server 2016) type in your search bar: Windows Firewall. You should normally get as first result this :

Basically the connection is blocked, you have to check the box I indicated.
Leave everything checked off.
Put a name that is characteristic of the open port, and if you want a description for what the port is used for. Then click on "Finish".
