HTTP Error Codes - 401 Unauthorized

A 401 status code indicates that the request could not be authenticated. This may be caused by any one of these conditions:

  • No credentials supplied to Basic Authentication, and no Authorization Ticket cookie sent with the request.
  • An invalid username or password was supplied to Basic Authentication.
  • An expired or invalid Authorization Ticket cookie sent with the request.

The typical course of action would be to include Basic Authorization credentials and resend the request.
