    Description

      [Windows]: With some https URLs there is no read notification during the handshake phase so it just ends up failing. This however does not happen on Mac and also works fine with other https URLs too.

      The debug output for the URL - https://gsu.view.usg.edu - is:

      QAbstractSocketPrivate::flush() 330 bytes written to the network
      QSslSocket::_q_bytesWrittenSlot( 330 )
      

      This was done with the securesocketclient example setting the port to 443, doing the same thing with www.amazon.co.uk works fine.
