You might want to read about port binding and how passenger detects node apps starting: https://www.phusionpassenger.com/docs/advanced_guides/in_depth/node/reverse_port_binding.html there isn't a nest.js example but the problem you need to address is covered there.

Thanks for the reply, Cam.

I have already tried that without any success.

Nest.js uses Express as the http engine but wraps it which I think is what is masking the call.

Are you able to show an example Nest.js setup similar to the Express example shown in your link?
