body: <p>I'm having a problem with nginx configuration.</p>
  
  <p>When I set the configuration like this:</p>
  
  <pre><code> server {
           server_name redmine;
          listen       80;
  
          location / {
             proxy_pass http://172.16.0.70:33000;
          }
  }
  </code></pre>
  
  <p>I get this error nginx: [emerg] unknown directive "proxy_pass".</p>
  
  <p>My nginx version is nginx/1.8.0.</p>
