ReflectionException in Route.php Class Controller does not exist

I'm using Laravel 5.2 in a centos 5.8 server and getting the following error:

ReflectionException in Route.php line 280:
Class xxxx\Http\Controllers\CpanelController does not exist


ErrorException in ClassLoader.php line 412: include(/home/xxxx/vendor/composer/../../app/Http/Controllers/CpanelController.php): failed to open stream: Permission denied

Im trying with:

php artisan cache:clear

chmod -R 777 storage

composer dump-autoload

But the problem persists
