socket error ProxyProtocolError

[Talei]

Hello,
I have a problem with setting up proxy in QTcpSocket.
I do this by the manual, i.e. set up proxy type, ip, port, set proxy in socket and then connect to i.e "google.com".

Connection states are (signals: stateChanged and error):

state changed: QAbstractSocket::HostLookupState
state changed: QAbstractSocket::ConnectingState
state changed: QAbstractSocket::UnconnectedState
--- sockError error: QAbstractSocket::ProxyProtocolError

I know that proxy is working (checked with FF, it's HTTP proxy) but I don't know why QTcpSocket throw this error.

So the question what this mean: ProxyProtocolError? I read SocketError-enum (http://doc.qt.nokia.com/4.8/qabstractsocket.html#SocketError-enum) but it's unclear to me what this actually means.

Thanks for reply.
Regards
