Container not ready on cold start - "not listening on TCP address" error

Hi, I have a docker container of a Laravel application built with frankenphp and every time I send a request when the container is in "Ready" state it fails with the following error:

Container error: The container is not listening in the TCP address 10.0.0.1:8080

After some seconds (like 2-3 seconds) I do the exact same request and it returns correct data...

Any idea on how to fix this? Have seen the docs but can't figure it out.

Reproduce the cold-start request against the Dockerized Laravel/FrankenPHP container and inspect startup logs alongside the readiness state. Done means a request sent immediately after the platform reports Ready succeeds without the TCP-listening error, rather than only succeeding after the reported 2–3 second delay.
