Ranch listener no route found for GET /css/app.css

I am new to Phoenix and Elixir and trying to start with a few projects. I am trying to add tailwindcss to a project but i am running in to an issue where on mix phx.server the Router cannot find /css/app.css and /js/app.js. I haven’t had this issue before when not using tailwind.

i have tried updating the Routes.static_path(@conn, “/css/app.css”) to “/static/css/app.css” and still no luck. I followed this guide: Install Tailwind CSS with Phoenix - Tailwind CSS when trying to install tailwind.

Any suggestions would be appreciated I have been trying to fix this for a while now.
Thanks!

Phoenix comes with tailwind built in on the latest major release.

Yes, I just figured out that I had the wrong Phoenix version installed. Thank you!
