title: Did Not Connect: Potential Security Issue
body: <p>Not able to continue visiting my local development website. Because browsers are blocking the site and common problem is <strong>HSTS</strong>. Unable to figure out what's gone wrong.</p>
  
  <p>Recently I setup new system for web development. Everything was working well since I setup new machine. Sudden today everything got freeze and I feeling like prisoner.</p>
  
  <p>Firefox and Google Chrome was blocked site last week, still my work was continuing because Firefox Development Edition was holding my back. And was also exploring to fix that issue. But today it is got over. So, I finally on fixing this.</p>
  
  <p>Only difference between two machine is OS and Web Server. On old machine (macOS) I was using Apache, but Nginx is on my new machine (Ubuntu).</p>
  
  <p>Our live production domain is <a href="https://www.peoplematters.in" rel="nofollow noreferrer">https://www.peoplematters.in</a> and we do development using <a href="https://dev.peoplematters.in" rel="nofollow noreferrer">https://dev.peoplematters.in</a>.</p>
  
  <p>For local development I'm using self signed certificate.</p>

  <p>In some cases browser's allow to add security exception. But in this HSTS case it is not allowing. I've not configured HSTS header for local development version. So, why it's showing!!!</p>
