My Vercel projects return 404 NOT_FOUND on / even though deployments are READY, production domains are valid, and Deployment Protection is disabled.

The Next.js build completes successfully and lists / as a route, but requests never reach the application or functions.

Request ID: gru1::f4knn-1790041616633-f27f10686bc7

Affected project: wa6x20/padaria-rebeca-loja

I also created a new clean Vercel project and get the same result. Any idea why the deployment is not being served?
