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

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

To copy to clipboard, switch view to plain text mode 

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 but it's unclear to me what this actually means.

Thanks for reply.
Regards
