title: nginx - Disable http to https redirect?
body: <p>I followed this tutorial <a href="http://www.schenkels.nl/2014/12/reverse-proxy-with-odoo-8-nginx-ubuntu-14-04-lts/" rel="noreferrer">http://www.schenkels.nl/2014/12/reverse-proxy-with-odoo-8-nginx-ubuntu-14-04-lts/</a> how to make reverse proxy for odoo with nginx. </p>
  
  <p>Everything went fine here. But the problem is with certificate.
  Every browser swears that my self signed certificate is not trusted. And this is test server so I don't really care about security now. I tried to disable/comment everything with certificates and ssl. But nginx still redirects to https and then when it does not find certificate, it just gives this error:</p>
  
  <pre><code>Unable to make a secure connection to the server. This may be a problem with the server, or it may be requiring a client authentication certificate that you don't have
  </code></pre>
  
  <p>But how can I make to just ignore <code>https</code>, and use <code>http</code> instead without any encryption? Do I need to adjust something inside nginx itself?</p>
  
  <p>For example using apache, if not specified to use secure connection, then it just uses normal <code>http</code> and that is that. Hope someone else have better experience with nginx.</p>
  
  <p>Configuration I adjusted looks like this (I just commented some parts and changed rewrite to be <code>http</code> instead of <code>https</code>):</p>
  
  <pre><code>upstream odoo8 {
  server 127.0.0.1:8069 weight=1 fail_timeout=0;
