Ask Ubuntu is a question and answer site for Ubuntu users and developers. It's 100% free, no registration required.

I'm trying to host a small node application on a digital ocean droplet running ubuntu 14.04. In local development the site works fine over https, however on the server the site doesn't get displayed and the server does not throw an error, the connection is just refused. I ran nmap localhost and port 443 was closed. How can I open it?

Is your web server configured for HTTPS? –  kraxor Jul 20 at 8:56

sudo ufw allow 443/tcp

And have a read through the docs on Ubuntu UFW interface on iptables. This should open it for your web application.

Also make sure that your application is serving off the external IP as well as the internal. The app.js file there is usually a setting to specify a interface for it to run on. 0.0.0.0 should run it on both internal and external.

When I run sudo ufw status verbose it says inactive. Should I sudo ufw enable? Because it's inactive it isn't the thing that's closing the port then right? –  Wilfred Jul 20 at 14:38
