title: Freshly installed nginx not serving default page
body: <p>I just installed nginx on a new ubuntu instance.  It looks like nginx is running, here are the processes:</p>
  
  <pre><code>root      2062  0.0  0.1  85868  1340 ?        Ss   01:13   0:00 nginx: master process /usr/sbin/nginx

  </code></pre>
  
  <p>Also here is sudo nstat -plnt</p>
  
  <pre><code>tcp        0      0 0.0.0.0:22              0.0.0.0:*               LISTEN      1076/sshd       
  tcp        0      0 0.0.0.0:80              0.0.0.0:*               LISTEN      2062/nginx

  <p>But when I go to my public ip address (I don't have any sites configured) my browser times out and the default nginx page is not displayed.</p>
  
  <p>There are no errors in the nginx log and sudo nginx -t looks fine.  I followed some tuts to get it installed and started, but everyhthing says it should immediately serve the default homepage.</p>
  
  <p>Here is what is in my /etc/nginx/sites-enabled</p>
  
  <pre><code>server {
      listen 80 default_server;
      listen [::]:80 default_server ipv6only=on;
  
      root /usr/share/nginx/html;
      index index.html index.htm;
  
      server_name localhost;
  
      location / {
              try_files $uri $uri/ =404;
      }
  }
  </code></pre>
