title: Visual Studio 2019 SSL/TLS secure channel issues
body: <p>I installed VS 2019 with latest updates/patches. My Windows 10 Enterprise is also fully updated. Unfortunately I can't install any extension from Tools > Extension Manager.</p>
  
  <p>It's always complaining about request abortion.</p>
  
  <pre><code>The request was aborted. Could not create SSL/TLS secure channel.
  </code></pre>
  
  <p>Also it's impossible to load <code>NuGet</code> official packages with same error message.</p>
  
  <p>To make it clear:</p>
  
  <ol>
  <li><p>I repaired VS installation</p></li>
  <li><p>I enabled all available SSL protocols through Internet Options > Advanced > Settings (SSL 3, TLS { 1.0, 1.1, 1.2, 1.3 })</p></li>
  <li>I disabled Windows Firewall completely</li>
  </ol>
  
  <p><strong>UPDATE</strong></p>
  
  <p>I've been busy for couple of days and tonight I've got a time to check it out again. Surprisingly it's working now. I don't know what is happened, may be it was a problem with my internet connection or it was my chance to spend a lot of time to investigate with issue.</p>
