Quick Laravel Troubleshooting Help

Hey everyone,

I'm hitting a bit of a wall after pushing a new feature live to production this morning. Everything worked perfectly on my local setup, but now I'm seeing unexpected errors on the live server. Specifically, I'm getting a Class 'App\Http\Controllers\Admin\ProductController' not found error, even though the controller is definitely there, and the namespaces seem correct. I've already tried running composer dump-autoload multiple times, and even php artisan config:clear, but no luck. This is causing some significant Laravel deployment issues for our users right now.

Here's a snippet from the error log:

[2023-10-27 10:30:05] production.ERROR: Class 'App\Http\Controllers\Admin\ProductController' not found {"exception":"[object] (Symfony\Component\Debug\Exception\FatalThrowableError(code: 0): Class 'App\\Http\\Controllers\\Admin\\ProductController' not found at /var/www/html/vendor/laravel/framework/src/Illuminate/Container/Container.php:803)
[stacktrace]
#0 /var/www/html/vendor/laravel/framework/src/Illuminate/Container/Container.php(803): ReflectionClass->__construct('App\\Http\\Contro...')
#1 /var/www/html/vendor/laravel/framework/src/Illuminate/Container/Container.php(681): Illuminate\\Container\\Container->build('App\\Http\\Contro...')
#2 /var/www/html/vendor/laravel/framework/src/Illuminate/Foundation/Application.php(796): Illuminate\\Container\\Container->resolve('App\\Http\\Contro...', Array)

What are your go-to quick fixes or common troubleshooting steps when facing such "Class not found" issues in Laravel, especially right after a deployment? Any seasoned advice on what I might be missing would be greatly appreciated!

Thanks in advance!
