Why are my Symfony Router are not Working?

I am currently creating a Symfony Project for School and i was just trying some things out with this Security Bundle… I was creating the Registration Controller with this php bin/console make:registration-form Command and it worked out fine. The Files got created and i got no Errors but when i am trying to go to /register they just show me my index.php all the time… if i delete index.php its always # Page not Found from my Symfony Local Server… Im just testing out so im just using this localhost Webserver from Symfony. I tested out the Route with php bin/console router:match /register and it showed green, it works and exists. But when i try going to the Site nothing happens.
