Unlike in the case of the unable to connect to proxy server error, in the case of authentication, the connection went through, but the server required an authentication and wasn't successful.

Providing an acceptable authentication method should clear the error.

However, most apps will disregard it. you will need to make use of a proxy client that will force all of your requests via the proxies for it to work.
