Authentication with the proxy is required

Specification of the HTTP status code 407

The 407 Proxy Authentication Required status code is similar to 401 (Unauthorized), but it indicates that the client needs to authenticate itself in order to use a proxy. The proxy MUST send a Proxy-Authenticate header field (Section 4.3) containing a challenge applicable to that proxy for the target resource. The client MAY repeat the request with a new or replaced Proxy-Authorization header field (Section 4.4).

Source / Quote by: The 407 Proxy Authentication Required HTTP Status Code is specified by section 3.2 of RFC7235.
