What are some reasons why "401" errors on websites?
user
Auto-code-generated website error messages are mostly created with the code 401, indicating that the website is unauthorized or unauthenticated. This is a general error type, and can indicate the lack of proper authorization, accessing or signing-in to a website or internet browser.  In most cases, the 401 error results from an incorrect or malfunctioning username/password combination.  I recommend verifying the login credentials and trying to re-sign in or contact an administrator.

A 401 error happens when a website recognizes that you have requested access to a restricted area or part of the website.  Often a 401 error page shows up when users visit "member-only" areas, such as exclusive personal or account-manager pages.  Some 401 errors can also happen if a newly installed website is not fully functioning, or if links have been mistyped.  If you encounter a 401 error on a website or are trying to access a restricted part of a website, it's best to first make sure that the website content is available to anyone rather than just registered users.  If you don't have a registered user account or membership, the best way to access the restricted area is to first register for an account
