title: TLS connection error 'This might be because the site uses outdated or unsafe TLS security settings.'
body: <p>I am performing an upgrade of a web application for which I have to configure the website on IIS10 on a new server. While setting up, I had provided DNS which is exactly same as the DNS on the old server.</p>
  
  <p>To access the newly configured website I have paused old IIS and I am accessing the new one. Then I am getting below error</p>
  
  <blockquote>
    <p><em>This might be because the site uses outdated or unsafe TLS security settings. If this keeps happening, try contacting the website’s owner.</em></p>
  </blockquote>
  
  <p>What could be the reason, is it because both, old and new have the same DNS?
  Is there anything that I need to find out? I have checked with <code>eventvwr</code>, nothing is shown there.</p>
  
  <p>Also note, TLS 1.0, 1.2 values are active.</p>
