Observed message
Container failed to start. Failed to start and then listen on the port defined by the PORT environment variable.
Why it happens
The application is listening on the wrong port.
The container process fails before the server starts.
Startup logic prevents the container from binding to the expected port in time.
How to fix it
Update the app to listen on the port provided by the PORT environment variable.
Run the container locally to confirm it starts successfully.
Check startup logs for crashes or misconfiguration before the server binds.
