title: Self-signed trusted root certificate is not recognized by Edge
body: <p>For development, my team is using a self-signed SSL certificate.  After installing the certificate in my machine's Trusted Root Certification Authorities store, the SSL certificate is recognized as valid in Chrome and IE 11:</p>
  
  <p>Internet Explorer 11:</p>

  <p>Chrome 69:</p>

  <p>But Edge (version 42) seems to be ignoring the certificate:</p>

  <p>Based on the message I'm getting from Edge ("This might be because the site uses outdated or unsafe TLS security settings"), I thought that my local development server might be using an outdated TLS version, but I can verify in Chrome's development tools that traffic is being encrypted using TLS 1.2:</p>

  <p>Why does Edge seem to be ignoring my self-signed certificate that I have installed as a Trusted Root Certificate? How can I fix it?</p>
  
  <p>Things I've tried:</p>
  
  <ul>
  <li>Installing the same certificate in my Personal and Intermediate Root Certification Authorities stores</li>
  <li>Restarting my machine</li>
  </ul>
