title: ASP.NET The underlying connection was closed: Could not establish trust relat
body: <p>When attempting to use HttpWebRequest to retrieve a page from my dev server, I get a web exception:</p>
  
  <p>The underlying connection was closed: Could not establish trust relationship for the SSL/TLS secure channel." The remote certificate is invalid according to the validation procedure...</p>
  
  <p>The url I'm attempting to read from is a plain-old <a href="http://myserver.com/mypage.asp" rel="nofollow noreferrer">http://myserver.com/mypage.asp</a> - no SSL. The production server has a valid certificate so this shouldn't be an issue, but our dev server doesn't. </p>
  
  <p>Help!</p>
