title: HTTPS load balancer in Google Container Engine
body: <p>I'm trying to set up an HTTPS load balancer for GKE using <a href="https://cloud.google.com/compute/docs/load-balancing/http/#https_load_balancing" rel="noreferrer">HTTPS L7 load balancer</a> but for some reason is not working. Even the HTTP load balancer in the <a href="https://cloud.google.com/container-engine/docs/tutorials/http-balancer" rel="noreferrer">HTTP Load Balancing walkthrough</a>. The forwarding rule's IP address is created and I'm able to ping and telnet to port 80. But when request via curl it give me a error. </p>
  
  <pre><code>&lt;title&gt;502 Server Error&lt;/title&gt; &lt;/head&gt; &lt;body text=#000000 
  bgcolor=#ffffff&gt; &lt;h1&gt;Error: Server Error&lt;/h1&gt; &lt;h2&gt;The server 
  encountered a temporary error and could not complete your request. 
  &lt;p&gt;Please try again in 30 seconds.&lt;/h2&gt; &lt;h2&gt;&lt;/h2&gt; &lt;/body&gt;&lt;/html&gt;
  </code></pre>
  
  <p>All the steps were fine and I created a firewall without any tags for the ${NODE_PORT} but it didn't work. </p>
  
  <p>Has anyone encountered this problem?</p>
