407 Proxy Authentication Required
You must authenticate with a proxy server before this request can be serviced.
Please logon to your proxy server and then try again.
The Web Proxy, through a 407 HTTP response, requests credentials from the browser client (or downstream Proxy Server). The client provides the credentials, or in the case of a downstream Web proxy, the proxy server may provide the credentials itself.
If the credentials used by the client or by the downstream proxy server are not allowed by the upstream proxy server, this error will be displayed.
