Stop NGINX dev site redirecting to SSL - ssl

Question

I have a Ruby on Rails app running on a Linode Server and I am trying to create a staging server to do some testing on. I cloned the Linode and have the server up. I am able to visit the site, however, I get the 'not secure' error in Chrome, so I want to turn ssl off. So in /etc/nginx/sites-enabled/nginx.conf I commented out listen 443 ssl; and also commented out the lines referencing ssl_certificate and ssl_certificate_key. In /etc/nginx/nginx.conf I commented out ssl_protocols and ssl_prefer_server_ciphers. After doing this I have restarted nginx.
When I visit the IP address, the address part redirects to SSL and I get a message that says This site can’t be reached. Why is the site still redirecting to ssl? Am I missing a configuration somewhere?
EDIT
Here are nginx.conf:
