On Windows 7 and on my work network I am behind a Bluecoat proxy.
When I try to connect to a WebDAV server using HTTP or HTTPS cyberduck keeps waiting to list files, but never does. The exact same connection profile works perfectly fine when not behind the prox.

After a long wait I sometimes get a popup window that says that Cyberduck cannot connect to the proxy address, if I specified it in my settings. The proxy is working fine for my browsers (using it now). Error message is "Connection timed out: connect."

The "Log Drawer" is empty
