502 error on CI test (Check PWA reachability) on a fresh install

[ibousfiha]

API Platform version(s) affected: 4.0.11, main

Description
When running e2e tests in GitHub Actions on a fresh install of an API Platform instance (using both the 4.0.11 tag and the main branch zip), a 502 error is returned when checking the reachability of the PWA - Error: curl: (22) The requested URL returned error: 502.

The test case that fails is the following:

      -
        name: Check PWA reachability
        run: "curl -vk --fail-with-body -H 'Accept: text/html' https://localhost"

in: .github/workflows/ci.yml

How to reproduce

1. Download the API Platform repository (either version 4.0.11 or the current main branch).
2. Push to a new Repository (mine was private)
3. Check Github Actions

Possible Solution
I tried hard to find one but I didn't.

Additional Context
I checked this issue: #2694 which seems similar to mine, but the suggested solution didn't solve it.

Closing per #2987 — this repository is becoming a CLI installer. The previous Docker/template distribution is being superseded by the installer + upstream symfony-docker. If the issue still reproduces with the new setup, please open it on dunglas/symfony-docker (for Docker/Caddy/FrankenPHP issues) or api-platform/core (for framework issues).
