I'm pretty new to the DevOps world so I believe it is likely I'm missing something simple or not looking in the right places.
I have deployed a Ruby on Rails application to an Ubuntu Server (on Linode). To complete the deployment I use Capistrano 3, Nginx, and Puma. From what I can tell the deployment is entirely successful. There are no errors in the Puma, Nginx, or Rails logs. Puma is running. However, when I try to access the site via a web browser I get a Connection Refused error.
I'm not sure if it's port related, but running sudo netstat -ntlp | grep LISTEN outputs this, which to my knowledge is correct:
tcp 0 0 0.0.0.0:80 0.0.0.0:* LISTEN 29940/nginx: master

Running sudo ufw status numbered outputs this:

Let me know if I should add any configuration files. What would cause the connection to be refused?
