You can't specify credentials to a proxy this way.  The first element of
the address tuple for an AF_INET socket is a hostname or IP address.  If
you have a proxy which requires authentication, you must authenticate
after you have established the connection by sending bytes over the socket.

I don't know what kind of proxy you have, so I don't know what bytes you
have to send.
