Symfony Apache External Redirections - php

Question

I've done a URL shortener app for my server side programming subject.
For fun I decided to deploy it on a web server, in this case the oracle free tier with an ubuntu server with apache, and I also adquired a public domain.
In my local environment all works fine using the symfony local server:
symfony server:start
But once I deployed the app the redirections doesn't work anymore.
All occur on the home page, the user types the URL to shortener( and the new 'endpoint'), Symfony validates the URL and if it's the case the new 'endpoint', then if all it's valid store the data and also in the home shows the new URL (ex. '/hjas8ab') that the user needs to paste it behind my domain (ex. mydomain.xyz/hjas8ab) and then Symfony checks that the 'endpoint' is associated to an URL in the database and redirects the user to that URL. And is in this step that the app deployed fails, even if I hardcode the URL to redirect.
So I think it's the Apache virtual host configuration, but I'm not sure.
Here is the code:
ShortenerController.php

return $this->forward('App\Controller\UrlAddressController::redirection', ['finalRedirection' => $url]);
}
if(!is_null($endpoint)){
return $this->render('shortener/index.html.twig', [
'created' => $created, 'endpoint' => $endpoint, 'autogenerated' => $autogenerated
