title: upstream timed out (110: Connection timed out) while connecting to upstream
body: <p>I wanted to deploy my Django website on port number 8000 in my AWS ec2 instance of the ubuntu machine. But after running the Nginx server, I'm getting the following 400/Bad request error in the browser, and in the Nginx error log, it's showing as follows.</p>
  <pre><code>upstream timed out (110: Connection timed out) while connecting to upstream, client: 23.104.74.85, server: , request: &quot;GET / HTTP/1.1&quot;, upstream: &quot;http://2.12.52.96:8080/&quot;, host: &quot;2.12.52.96&quot;
