DigitalOcean Droplet IP address not working

Question

I created my first droplet, but when I try to navigate to the provided IP address like http://my_ip_address, it shows This site can’t be reached in the browser.

This is the tutorial I used to create the droplet, and I got my web app from github.

Do I also need to install a webserver like Apache? The tutorial didn't say anything about needing to do that.

Answer 1

Port 3000 is blocked by Digital Oceans firewall. Available ports are 22, 80 and 443. You could also try

sudo ufw allow 3000/tcp
