WSAECONNREFUSED (10061): "Connection refused."

WSAENOTCONN (10057): "Socket is not connected."

It is obvious that transient_internet() should catch WSAECONNREFUSED, but for WSAENOTCONN, I don't understand why it happens on a SSL handshake.

Attached patch catchs both errors. We may start with only WSAECONNREFUSED, and maybe add a specific code for test_ssl?
