title: nginx -t fails due to server_names_hash_bucket_size - but changing the size does not resolve the issue
body: <p>I am launching a Django application using gunicorn and nginx through AWS. I set up the gunicorn configurations with no errors. I created a new nginx configuration in <code>/etc/nginx/sites-enabled</code> and I ran <code>sudo nginx -t</code> to see test and I get the following errors: <br>
  <code>nginx: [emerg] could not build server_names_hash, you should increase server_names_hash_bucket_size: 64
  nginx: configuration file /etc/nginx/nginx.conf test failed</code><br><br>
  I uncommented the <code>server_names_hash_bucket_size: 64</code> in nginx configurations at <code>etc/nginx/nginx.conf</code> and this still does not change my error and I am not able to restart my server (I am trying to set up a supervisor to ensure gunicorn is always running in the background) <br>
  For reference: <br> <b>django.conf: </b><br></p>
  
  <pre><code>server { 
     listen 80; server name 34.212.49.238; 
     location / { 
        include proxy_params; 
        proxy_pass http://unix:/home/ubuntu/Django_webapp/app.sock; 
     } 
  } 
  </code></pre>
  
  <p>I also ran <code>systemctl status nginx.service</code>: <br>
