Qt Code: 
  1. incomingConnection 
  2. Stan:  QAbstractSocket::ConnectedState 
  3. Blad:  QAbstractSocket::SocketError( 13 ) // The SSL/TLS handshake failed, so the connection was closed (only used in QSslSocket)
  4. Stan:  QAbstractSocket::UnconnectedState

I do not know why QList<QSslError> l is empty.
