Deploying a NestJS app - deployment stuck at "In progress"

2

I finally figured it out. I’m using the Fastify adapter instead of Express, and here’s what I found straight from the docs:

By default, Fastify listens only on the localhost 127.0.0.1 interface (read more). If you want to accept connections on other hosts, you should specify '0.0.0.0' in the listen() call:

So I changed:

await app.listen(port)

to

await app.listen(port, '0.0.0.0');

and it works great now. I hope this helps someone else down the road!
