Symfony remove "index.php" from twig generated path

Question

I have just set up a new Symfony 5 application with a basic Twig template, routing using annotations.

I have routes set up for 'home' and 'terms and conditions' pages:

<?php

namespace App\Controller;

use Symfony\Bundle\FrameworkBundle\Controller\AbstractController;
use Symfony\Component\Routing\Annotation\Route;

class GeneralController extends AbstractController {

    /**
     * @Route("/", name="main_home")
     */
    public function homePage() {
        return $this->render('general/home.html.twig', ['title' => "Welcome"]);
    }

    /**
     * @Route("/terms", name="terms_and_conds")
     */
    public function termsAndConditions() {
        return $this->render('general/terms.html.twig', ['title' => "Terms and Conditions"]);
    }
}

These both work fine when I point my browser at:

https://example.com/

https://example.com/terms

In my Twig base template, I want to provide a link to the "terms" page:

<a href="{{ path('terms_and_conds') }}">Terms of Use</a>

however the URL which is generated is

https://example.com/index.php/terms

How do I ensure that the correct link is generated, excluding the index.php?

My /routes/annotations.yaml is:

controllers:
    resource: ../../src/Controller/
    type: annotation

kernel:
    resource: ../../src/Kernel.php
    type: annotation

I am running Symfony 5.0.4 on PHP 7.4.2 as FPM application served by Nginx on CentOS 7 with Plesk Obsidian.

Edit:

Here's my nginx.conf

Note that this is generated by Plesk and I am unable to change it directly, however I can do what I want in the included vhost_nginx.conf file.

Answer 1

Replace:

if (!-f $request_filename) {
    rewrite ^/(.*)$ /index.php last;
}

With:

location / {
    try_files $uri /index.php$is_args$args;
}
