What does "419 Page Expired" mean in Laravel 5.8 after logging in?

edit

A 419 page expired error in Laravel 5.8 after logging in generally means that the CSRF token validation failed or the authenticated session expired. Laravel uses CSRF tokens to protect against cross-site request forgery attacks. When a user logs in, Laravel assigns them a session and a CSRF token. If the user's session expires due to inactivity or the CSRF token is invalid, Laravel throws a 419 page expired error. To fix this issue, you can try clearing your browser cache or increasing the session timeout duration in your Laravel application.
