cyberduck 4.0.2(for windows 32bit) illegal sending HTTP request.

When I open a Cyberduck connection with the server on port 8080, i have a login failed.

In the official administrator guide documentation, the password syntax has to be the following:
"Password: Enter the password for the account and user name entered above."

at the time swift-proxy-server logging following message.
