Laravel Hosting

I have been having this error while trying to move from files from local server to a subdomain created. it shows this error "Forbidden

You don't have permission to access / on this server.

Additionally, a 500 Internal Server Error error was encountered while trying to use an ErrorDocument to handle the request."

Let me also add, I have tried replacing the files on the server with a simple html file and it works fine also it works fine on localhost. It is obvious that the issue is from my laravel code

I need help please!
