title: Envoy shows no healthy upstream
body: <p>I'm trying to build an envoy proxy by the help a <a href="https://piotrminkowski.wordpress.com/2017/10/25/envoy-proxy-with-microservices/" rel="noreferrer">blog</a> and I'm getting a bit of problem there.</p>
  
  <ul>
  <li><p>First of all, the blogs fixes the ip address and also it wildcard matches with any URL keeping the only thing important as port but when I tried to run the URL <code>http://192.168.99.100:9901/</code> for admin commands as given in blog it was not opening while when I tried it with my IP, it ran successfully.</p></li>
  <li><p>And also, I'm having problem with opening the webpage of the person service or product service on browser either by <code>http://192.168.99.100:10000/person</code> that is provided in the blog or by using <code>http://&lt;myip&gt;:10000/person</code> both of them displays <code>no healthy upstream</code> in the browser and in postman and I've no idea regarding <code>no healthy upstream</code>.</p></li>
  </ul>
  
  <p>I'm not using zipkins. </p>
  
  <p>I've seen questions related to <code>no healthy upstream</code> but I couldn't find an answer that can solve this problem.</p>
  
  <p>Please help.</p>
