HTTP Status Code 401

The status code 401, also known as "Unauthorized," indicates that you don't have the necessary permission to access a specific resource. This happens when you try to access a webpage or file that requires authentication, but you either haven't provided credentials, or the credentials you provided are incorrect or expired.

Here's a breakdown of what a 401 error means:

  • Client-side error: The issue lies with the way your request was formatted or the information you included.
  • Missing or incorrect credentials: You likely didn't enter a username and password, or the ones you entered were wrong.
  • Expired credentials: Your session may have timed out, or your authentication token might no longer be valid.

The way a 401 error displays can vary depending on the website. You might see a generic error message or a login prompt.
