title: How to solve google chrome "Failed to load resource: net::ERR_CONNECTION_REFUSED" issue in windows 10 when server is running on Ubuntu 18.04?
body: <p>I am trying to run this <a href="https://github.com/intuinno/conceptvector" rel="nofollow noreferrer">project</a> on Ubuntu 18.04 server. I am running both server and client on this machine. Then from windows 10 with port 9000 I am getting access to client in my chrome browser at <a href="http://localhost:8000/#/" rel="nofollow noreferrer">http://localhost:8000/#/</a></p>
  
  <p>The browser loads the project but the problem is I can't log into the website with trusted account and some other data do not get loaded . When I see browser console I see an error message saying: </p>
  
  <blockquote>
    <p>Failed to load resource: net::ERR_CONNECTION_REFUSED</p>
  </blockquote>
  
  <p>This is the server setting:

  <p>This is the client setting and putty setting to connect to client.

  <p><strong>VPN has been used to connect to server via PuTTY</strong>.</p>
  
  <p>The error message in browser:

  <p>Could anyone shed some light on this issue? Is it related to windows 10 or VPN or some other issues?
