By default, the built-in Windows Firewall will block inbound and outbound traffic from unknown applications. If, after installing and running a program on your Windows server, the application seems to not be accessible externally over the internet, you may need to allow the program through the Windows Firewall for inbound and outbound connections.
This guide is intended for Hostwinds clients who are using Windows on their Cloud VPS or Dedicated Server.
