My server only works on localhost but not works on ip address.

Hello, I’m using ubuntu 20.04 droplet. I’ve seen many tutorials that talked me that I don’t need many things to see my app run on the internet. They said that just run “pm2 start app_name” and then I can see my website on the internet by send my browser to “server_ip_address(ipv4):port_number”. In video, that works. But not for me.

When I try “curl http://localhost:port_number” or “curl” in server connected bash, it works. But when I try to connect by ip address outside of server computer(or bash) the browser load page endlessly. I can’t get any logs both in digitalocean graph and pm2, about my attempt using ip address.

It happens even before I install nginx to server. I’ve heard that after install nginx, i can default nginx html when I get to my server ip address, but that also does not work.

Why does this happens? I can’t get where does this problem comes from. Because I use ipv6? Or because I set firewall which is in doc “Recommended Initial Droplet Configuration” ( And how can I solve that?

“netstat -plant | grep port_number” gives me this. tcp6 0 0 :::port_number :::* LISTEN PID/node

Hi @ecrout,

Can I ask you to provide us with your Nginx configuration file for your domain or default configuration file to see if there is anything that is out of order inside of it?
