Phoenix umbrella app with sub-domains on the same port

I'm trying to create a Phoenix umbrella project with several apps on the same port. With my current config I receive this error:

⧕ /m/i/d/p/e/portfolio on master * ⟩mix phoenix.server                                                                                                                                   13m 20s 412ms
==> rumbl

                ** (EXIT) {:listen_error, Persona.Endpoint.HTTP, :eaddrinuse}

The details of my umbrella project are that I currently have 3 apps. 1 app proxies requests to the other 2 apps. The proxy app is a basic plug app.

# /apps/proxy/lib/proxy/plug.ex
...
  def call(conn, _opts) do
    cond do
      conn.host =~ ~r{rumbl.} ->
        Rumbl.Endpoint.call(conn, [])
      true ->
        Persona.Endpoint.call(conn, [])
    end
  end
...

Persona app

# /apps/persona/config/dev.exs
...
config :persona, Persona.Endpoint,
  http: [port: 8080],
  debug_errors: true,
  code_reloader: true,
  check_origin: false,
  watchers: [node: ["node_modules/brunch/bin/brunch", "watch", "--stdin",
                    cd: Path.expand("../", __DIR__)]]

...

Rumbl.app

# /apps/rumbl/config/dev.exs
config :rumbl, Rumbl.Endpoint,
  http: [port: 8080],
  debug_errors: true,
  code_reloader: true,
  check_origin: false,
  watchers: [node: ["node_modules/brunch/bin/brunch", "watch", "--stdin",
                    cd: Path.expand("../", __DIR__)]]

My requirement is because I'm using nanabox.io for my development and deployment and it requires that all http/https be received on port 8080.

If your proxy endpoint receives all the traffic anyway, set the port of the other 2 to something random so the ports don't collide.
