I have been failing to deploy (tried 3 times without success).

I was wondering if anyone could help me out!

Taking a look at those logs, I think this might be the problem

Listening on http://0.0.0.0:3000

From your fly.toml, it looks like your app is configured as if it were listening on 8080, instead. You’ll also want to be listening on IPv6 if this app would need to talk to other Fly apps in your org.

Thank you!
I fixed that up and it deployed successfully!
