configure nginx as a webserver with puma for application without domain - nginx

Question

I have a cloud server and my application is on my server. I currently do not have a domain but i would like to use nginx as a webserver for my application. So i configured in the nginx the following for this application.
I do not have a domain so example.com is just used as a proxy_pass url but it doesnt seem to be working.
/etc/nginx/sites-enabled/example.com
upstream puma_example {
server unix:///home/deploy/sites/example.com/shared/tmp/sockets/example.sock;
}
server {
listen 80 ;
server_name example.com;
gzip on;
gzip_http_version 1.0;
gzip_disable "msie6";
gzip_vary on;
gzip_min_length 1100;
gzip_buffers 64 8k;
gzip_comp_level 3;
gzip_proxied any;
gzip_types text/css text/xml application/x-javascript application/atom+xml text/mathml text/plain text/vnd.sun.j2me.app-descriptor text/vnd.wap.wml text/x-component;
root /home/deploy/sites/example.com/current/public;
access_log /home/deploy/sites/example.com/current/log/nginx.access.log;
error_log /home/deploy/sites/example.com/current/log/nginx.error.log info;
location ^~ /assets/ {
gzip_static on;
expires max;
add_header Cache-Control public;
}
try_files $uri/index.html $uri #puma_example;
location #puma_example {
proxy_set_header X-Forwarded-Proto http;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $http_host;
proxy_redirect off;
proxy_pass http://puma_example;
}
error_page 500 502 503 504 /500.html;
client_max_body_size 25M;
keepalive_timeout 10;
}
When i run my rails application i can see that is running but i cant seem to link it via nginx. So when i so http://example.com, it doesnt load my application.
What am i missing? how do i get my application to connect locally via nginx with no domain name on my cloud server.
Any help is appreciated.

You can use your ip address, here is a simplified example.
upstream 127.0.0.1 {
server unix:///var/run/yourapp.sock;
}
server {
listen 80;
server_name 127.0.0.1;
root /var/www/yourapp/current/public;
location / {
proxy_pass http://127.0.0.1/;
proxy_set_header Host $host;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
}
}
