407 Proxy Authentication Error

The HTTP 407 Proxy Authentication Required error response indicates that the request had been unsuccessful due to a lack of valid authentication credentials for the proxy server.

Here are the steps we suggest when facing the error:

• Double-check your user:pass credentials in the Smartproxy Dashboard.
  • Try generating a new password if you cannot authenticate with proxy user credentials.
• If you use the Whitelisted IP authentication, check if you are connected to the same IP address.
