title: NSURLConnection Lost Connection
body: <p>I have an app with 100k+ users that connects using a SOAP web service.  Everything works fine for most users except sometimes using NSURLConnection I keep getting the error: </p>
  
  <pre><code>Error Domain=NSURLErrorDomain Code=-1005 "The network connection was lost." UserInfo=0xac16c70 {NSErrorFailingURLStringKey=https://mail.scripps.org:443/ews/Exchange.asmx, NSErrorFailingURLKey=https://mail.scripps.org:443/ews/Exchange.asmx, NSLocalizedDescription=The network connection was lost., NSUnderlyingError=0x133b0eb0 "The network connection was lost."}
  </code></pre>
  
  <p>This only happens for certain servers.  The servers have NTLM authentication which works 95% of the time but for some reason I'm getting the error and I have no idea why.</p>
  
  <p>Any help appreciated.</p>
