A 403 error, also known as an “Access Denied” response, occurs when a user attempts to access a webpage that is restricted due to security or configuration issues. This can be caused by a variety of factors, including:
* Bad or invalid links
* Configuration errors on the server side
* Insufficient permissions or authentication
When a 403 error is encountered, the browser typically displays an error message indicating that the request could not be satisfied and suggesting options such as retrying, aborting, or contacting the app or website owner for assistance.
