Signal isn't emitted from socket

Hi,

Signal readyRead() isn't emitted from socket. Why? In this video it's working well: http://www.youtube.com/watch?v=j9uAfTAZrdM

Thank you!

Why would it emit readyRead()? HTTPS servers do not send any data upon connection. The SSL handshake is initiated by the client.

Thank you for reply!

But in video it works!

Apparently the video does something else than your code. Does your connected() slot ever get called?

By the way, are you aware you are connecting to a service that expects an SSL handshake?
