I just got myself a Windows 2019 server VPS. It's unmanaged.

I'm trying to open port 3307. I added the port to the firewall under ingoing tcp/udp and outgoing tcp/udp (see screenshots below). I'm running a Django REST server on port 3307 (it's running at this time). After doing that the port still seems to be closed, a port checker also says it's closed.

As far as I know this is all I need to do to open a port in a Windows server, is there anything I'm missing? I also contacted the host and they confirmed that the port is not closed on their side.

  • closed usually indicates that nothing is listening on that port, not a firewall problem. Check if your service is actually running and configured to the port/interface you are checking. – Gerald Schneider Aug 18 '20 at 13:45
  • @GeraldSchneider Thanks but I'm hosting a Django server on port 3307, check the last screenshot (which I just added). – SJ19 Aug 18 '20 at 13:50

Your screenshot shows that your server only listens on the Loopback interface

You are trying to access it with a different interface. Configure your server to listen on all interfaces (usually

One way to do this is shown here:

python manage.py runserver
  • Yes now it works, thank you so much! Never knew about the difference between and Localhost is the same as right? – SJ19 Aug 18 '20 at 13:59
