[Interest] Odd Proxy Behavior

[Jason Kretzer]

Thanks Thiago.
===
Why this if? Why not always tell it to use the system configuration?
===

If there was a proxy detected should I not try to use it?  Or does the line below just automatically use whatever is set in "Internet Options"?
QNetworkProxyFactory::setUseSystemConfiguration(true);

Not changing anything else, I removed the if and just used the setUseSystemConfiguration(true) and had the same results.

===
Please try each of the following:
 1) both HTTP and HTTPS URLs
 2) turn off the Caching feature of the proxy and setApplicationProxy
 3) use QTcpSocket to open a connection to somewhere, on both ports 80 and 443
===

1) I tried both HTTP and HTTPS with the same results
2) I have no access to the proxy, unless this can somehow be turned off from code.
3) I have done this and both ports return false (see code below)
bool ServerCommunication::connectToPort(QString server, int port)
{
    QTcpSocket socket;
    socket.connectToHost(server,port);
    if(socket.waitForConnected(500)) {
        socket.close();
        return true;
    }
    socket.close();
    return false;
}

===
My guess: you forgot to deploy the OpenSSL libs.
===
First thing that I checked :)
