title: SSL_ERROR_UNSUPPORTED_VERSION when attempting to debug with IIS Express
body: <p>Created a new template ASP.Net Core 3.1 MVC web app. When I attempt to debug it using IIS Express I get the following error in firefox:</p>
  <blockquote>
  <p>Secure Connection Failed</p>
  <p>An error occurred during a connection to localhost:44354. Peer using
  unsupported version of security protocol.</p>
  <p>Error code: SSL_ERROR_UNSUPPORTED_VERSION</p>
  </blockquote>
  <p>I attempted to delete all of my localhost certificates with MMC, repair IIS Express to install a new one. When attempting to debug it asks me to trust the certificate, I press yes, but this error still appears.</p>
  <p>I am on windows 7 if that matters.</p>
