Wordpress on Ubuntu w/ Nginx

Question

I used this tutorial from DigitalOcean
I am not able to get my vps to work with just one wordpress site with nginx.
Eventually I want to have 2 Wordpress sites on 2 different directories on the same server.

I included all 3 .conf files wordress.conf, common.conf & multisite.conf just like it says in the tutorial.

nginx.conf

user www-data;
worker_processes 1;
pid /run/nginx.pid;

events {
    worker_connections 768;
}

http {
    sendfile on;
    tcp_nopush on;
    tcp_nodelay on;
    keepalive_timeout 65;
    types_hash_max_size 2048;
    # server_tokens off;

    # server_names_hash_bucket_size 64;
    # server_name_in_redirect off;

    include /etc/nginx/mime.types;
    default_type application/octet-stream;

    access_log /var/log/nginx/access.log;
    error_log /var/log/nginx/error.log;

    gzip on;
    gzip_disable "msie6";

    # gzip_vary on;
    # gzip_proxied any;
    # gzip_comp_level 6;
    # gzip_buffers 16 8k;
    # gzip_http_version 1.1;
    gzip_types text/plain text/css application/json application/x-javascript text/xml application/xml application/xml+rss textjavascript;

    include /etc/nginx/conf.d/*.conf;
    include /etc/nginx/sites-enabled/*;
}

My file in /etc/nginx/sites-enabled/example that is symlinked from /etc/nginx/sites-available/example

server {
  server_name example.com;
  rewrite ^/(.*)$ http://www.example.com/$1 permanent;
}
server {
  server_name www.example.com;  
  root /var/www/example;
  access_log /var/log/nginx/www.example.com.access.log;
  error_log /var/log/nginx/www.example.com.error.log;
  include global/common.conf;
  include global/wordpress.conf;
}

wordpress.conf

# WORDPRESS : Rewrite rules, sends everything through index.php and keeps the appended query string intact

    try_files $uri $uri/ /index.php?q=$uri&$args;
}

}

#Yeah! you did it.

common.conf

# Global configuration file.

    access_log off;

    }

    access_log off; log_not_found off; expires 30d;
}

multisite.conf

# Rewrite rules for WordPress Multi-site.
if (!-e $request_filename) {
  rewrite /wp-admin$ $scheme://$host$uri/ permanent;
  rewrite ^/[_0-9a-zA-Z-]+(/wp-.*) $1 last;
  rewrite ^/[_0-9a-zA-Z-]+(/.*\.php)$ $1 last;
}

I configured the wp-config.php file as well. Created my MySQL user and made sure the user has access to the database.
Also changed the permissions of /var/www/example with chmod -R 755 .

And I have nothing on my logs:
/var/log/nginx/www.example.com.access.log nor /var/log/nginx/www.example.com.error.log files have been created.

When I curl or telnet I get a connection refused
telnet xxx.xxx.xxx.xx or telnet example.com

Trying xxx.xxx.xxx.xx...
telnet: connect to address xxx.xxx.xxx.xx: Connection refused
telnet: Unable to connect to remote host

curl xxx.xxx.xxx.xx or curl example.com

`curl: (7) Failed to connect to xxx.xxx.xxx.xx port 80: Connection refused`
