laravel works on the php development server but on apache gives weird error

FatalErrorException in ProviderRepository.php line 146:
Class 'Tymon\JWTAuth\Providers\JWTAuthServiceProvider' not found

I'm using dingo api. It's weird because it was working normally but then suddenly it gives me this error. and the weirder part is that it works perfectly on the php development server php -S localhost:8000 -t public/ but with apache it gives me this error.
