Why am I getting a 401 status code on my Remix app with Node.js?

I am facing an issue with the Shopify CLI and Node.js app template (Remix) where, after running the commands, I receive a 401 status code and the app does not load. Strangely, it was working fine yesterday, and no changes have been made since then.


Also tried to create a new app and same issue, any ideas?

I have the exact same issue. Just created an app with remix and it won't even create the app menu because a 401 is returned. Let me know if you find a solution.

Hi @marsan957 

Try below steps 

Create folder [shopify_app]

cd shopify_app


Step 1


-> npm init @shopify/app@latest
    give app name [test-app]

    select remix (if you are developing app in remix)


Step 2


-> cd test-app


->npm run build


Start a local development server

-> npm run dev

-> open generated URL


Step 3


Install your app on your development store
