Hi, I’m trying deploy node project (using fastify v4)

I already run **flyctl launch**. Deploy successfull.

But I cannot reach the web when I hit the endpoint. There is no clue on the logs.

Need help.

Hi.

Strange.

I got a sample Fastify app (v3, but not sure what would have changed to break it) working. Maybe take a look to see what differs (e.g Dockerfile, server.js and fly.toml)?

I wonder if it’s the `::1` 🤔 This was my listen line which worked:

```js
try {
    await fastify.listen(process.env.PORT || 3000, '::')
} catch (err) {
    fastify.log.error(err)
    process.exit(1)
}

```

Something wrong on my Dockerfile, thanks for the help!
