New app not working

I have setup sample app in node.js, which has index.html and /api , calling any of these should give response. but when i am calling the auto generated url as it is giving 404 error. deployment is green and i am using url given in Visit button at deployments. I have tried few others as well. also to confirm if the auto generated urls are seen in deployment tab

https://3comma.vercel.app/ https://3comma-sandhuranjeets-projects.vercel.app/ both of these gives 404 error and not does any runtime log appear, even though it should write log every 1 min

call the url

There's another community post with 404 debugging tips that might be helpful. Please give these solutions a try and let us know how it goes.

A human should be around soon to offer more advice. But you can also get helpful information quickly by asking v0.

Are you using the VERCEL_URL env variable in your sample app? Might be helpful to see your code/setup to further diagnose.
