Solution:1

I think there are two primary points that you'll need to look into:

  1. Port 443 does not need to be open to do the installing of an SSL certificate. The SSL certificate (of a website I'm assuming since you're talking about port 443) should be already created and available to the web service being used on the server.
  2. You need a web service running (e.g. Apache or Nginx) and configured to listen on port 443. Opening the port on the firewall just makes it so that the service listening on that port can be reached externally.
