This error serves as a barrier preventing access to protected content, prompting users to authenticate themselves to view the desired resource.

Causes of the 401 Unauthorized Error

1. Incorrect Login Credentials

  • The most common cause involves entering incorrect login credentials. Users attempting to access password-protected pages must ensure the accuracy of their login information.

3. Server Misconfigurations

  • Server misconfigurations, such as improper permission settings or directory access restrictions, can lead to this error. It hinders users from accessing specific directories or files due to insufficient permissions.

4. URL Changes or Redirect Issues

Effective Solutions to Resolve the 401 Error
