HTTP Error 407 - Proxy Authentication Required

407 Status Code Explained

This code is similar to 401 (Unauthorized), but indicates that the client must first authenticate itself with the proxy. The proxy MUST return a Proxy-Authenticate header field containing a challenge applicable to the proxy for the requested resource. The client MAY repeat the request with a suitable Proxy-Authorization header field.


Why it Comes

The Web server (running the Web site) thinks that the HTTP data stream sent from the client was correct, but access to the URL resource requires the prior use of a proxy server that needs some authentication which has not been provided. This typically means you must log in (enter user ID and password) with the proxy server first.


Fixing 407 Error Code

A 407 error detected via a Web browser can often be resolved by navigating to the URL in a slightly different way e.g. accessing another URL for the proxy server first. Your ISP should be able to explain the role of the proxy server in their security setup and how you should use it.
