Elixir: Infinite Loop when running Config.Provider?

This looks related: Server down: "can't run hallpass" - #3 by luke - I’m getting a similar error message.

I tore down my app - removed all running child processes from the Elixir Application (see below)

Any ideas @mcintyre1994 @kurt @thomas ?

defmodule Fitclub.Application do
  # See https://hexdocs.pm/elixir/Application.html
  # for more information on OTP Applications
  @moduledoc false

  use Application

  def start(_type, _args) do
    IO.puts("Arrived: #{__MODULE__}")

    children = [
    ]

    # See https://hexdocs.pm/elixir/Supervisor.html
    # for other strategies and supported options
    opts = [strategy: :one_for_one, name: Fitclub.Supervisor]
    Supervisor.start_link(children, opts)
  end

  # Tell Phoenix to update the endpoint configuration
  # whenever the application is updated.
  def config_change(changed, _new, removed) do
    FitclubWeb.Endpoint.config_change(changed, removed)
    :ok
  end
end
