Phoenix: (Phoenix.Router.NoRouteError) no route found for GET /phoenix/live_reload/socket/websocket

After creating a new app without brunch or html and starting it up after install, we get this debug message constantly printed to the console

"(Phoenix.Router.NoRouteError) no route found for GET /phoenix/live_reload/socket/websocket"

What is your Phoenix version?

[satb]

Phoenix version 1.2.1

defp deps do
    [{:phoenix, "~> 1.2.1"},
     {:phoenix_pubsub, "~> 1.0"},
     {:phoenix_ecto, "~> 3.0"},
     {:postgrex, ">= 0.0.0"},
     {:gettext, "~> 0.11"},
     {:cowboy, "~> 1.0"}]
  end

Is it possible you have an "old" app running in another tab that included html support? That would explain the logs. If not, can you push your test app to a public repo so we can take a look? Thanks!

[satb]

@chrismccord - Thank you. You are right. There is a tab open with an old app. Sorry for the trouble.

I am getting the same issue and I don't have another app running.
I deleted an app with the same name before I created new one with --no-html --no-brunch flags.

@nikolal did you manage to solve your problem? I am facing this same issue.
