Getting errors when trying to remote in to my Fly.io app - any tips on troubleshooting?

I’m getting an error when I try to remote into my app on fly.io. In this case I’m just doing a basic read from iex. (I am using Ash but Zach is convinced it is not an Ash problem)

Unknown Error

Node.list() returns [], so I can see it’s definitely not connected. I had the DNS clustering stuff configured already except for the entry in fly.toml. I added that, deployed and am getting the same result.

I’m getting a warning in my logs on deploy:

WARNING The app is not listening on the expected address and will not be reachable by fly-proxy.asdfg reached started state
You can fix this by configuring your app to listen on the following addresses:
  - 0.0.0.0:8080

Do I need to change my endpoint configuration?

  host = System.get_env("PHX_HOST") || "example.com"
  port = String.to_integer(System.get_env("PORT") || "8080")

  config :twfex, MyAppWeb.Endpoint,
    url: [host: host, port: 443, scheme: "https"],
    http: [
      # Enable IPv6 and bind on all interfaces.
      # Set it to  {0, 0, 0, 0, 0, 0, 0, 1} for local network only access.
      # See the documentation on https://hexdocs.pm/bandit/Bandit.html#t:options/0
      # for details about using IPv6 vs IPv4 and loopback vs public addresses.
      ip: {0, 0, 0, 0, 0, 0, 0, 0},
      port: port
    ],
    secret_key_base: secret_key_base

Locally, it’s all fine.

Anyone have any ideas?
