I am in China, so I just try a new Phoenix project with mix phx.new hello，after this I run command mix setup, and the error:

13:48:38.322 [info] Migrations already up
[debug] Downloading tailwind from https://github.com/tailwindlabs/tailwindcss/releases/download/v3.4.0/tailwindcss-macos-x64
** (RuntimeError) Couldn't fetch https://github.com/tailwindlabs/tailwindcss/releases/download/v3.4.0/tailwindcss-macos-x64: {:error, :socket_closed_remotely}

This typically means we cannot reach the source or you are behind a proxy.
You can try again later and, if that does not work, you might:

  1. If behind a proxy, ensure your proxy is configured and that
     your certificates are set via the cacerts_path configuration

  2. Manually download the executable from the URL above and
     place it inside "_build/tailwind-macos-x64"

  3. Install and use Tailwind from npmJS. See our module documentation
     to learn more: https://hexdocs.pm/tailwind

I manually download tailwind-macos-x64, put it under _build dir, but when I start with mix phx.server I get No route found for GET /assets/app.css and the UI all mess.

And then I follow Tailwind — tailwind v0.5.1 change config/config.exs file this part:

config :tailwind,
  version: "3.4.0",
  hi: [
    args: ~w(
      --config=tailwind.config.js
      --input=css/app.css
      --output=../priv/static/assets/app.css
    ),
    cd: Path.expand("../assets", __DIR__)
  ],
  path: "../_build/tailwindcss-macos-x64"

Still not work, anyone can help me?
