Hi Railway Support,

I’m experiencing an issue deploying a PHP/Symfony application.

The build completes successfully and the deployment shows as successful, but the application does not respond once deployed. I consistently get a 502 Bad Gateway.

What’s strange is that this is not limited to my custom project — even official boilerplate/templates do not work on my side. The build logs show no errors, the deploy completes normally, but the app never responds.

Here is what I’ve already checked:

• Build completes without errors

• Deployment status shows “successful”

• No obvious runtime crash in logs

• Domain is generated properly

• No custom start command (also tested with/without one)

• Tried setting NIXPACKS_PHP_ROOT_DIR=/app/public

• Tried default networking configuration

It seems like the app process is either not binding correctly to the expected port or not being proxied properly, but logs don’t clearly indicate why.

Additionally, parts of the Symfony documentation for Railway appear outdated compared to the current UI/settings, which makes troubleshooting difficult.

Could you please help identify:

1. Whether the service is actually binding to the expected internal port

2. If there is a known issue with PHP/Symfony deployments

3. If there is an updated, working minimal example for Symfony on Railway

Thank you in advance — I’m currently blocked on deployment.

Best regards,
William
