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.
