When working with Laravel, one might occasionally come across a NotFoundHttpException error. This issue can be frustrating, especially when it feels like all your routes are defined correctly. However, a deeper look often reveals there are a few common causes:

Incorrect Route Definition
Laravel uses a straightforward syntax for defining routes, but a minor typo or missing segment can throw an error. Double-check to ensure that your routes are defined accurately in the routes/web.php file.

Web Server Configuration
Ensure that your web server (e.g., Apache or Nginx) is set up to direct all requests to Laravel’s public/index.php file. Configuration issues here can lead to routes not being processed correctly.

Parameter Mismatches
Route parameters must match the controller's method parameters. For example, if a route expects an ID parameter, ensure your controller method accounts for it.
