The deployed bundle shipped with no API base URL, so every request fell back to a relative /api/*, which the frontend's nginx forwards to a backend:8000 service this deployment does not have. The cause was this Dockerfile. Vite gives a real environment variable precedence over its .env files, so `ARG VITE_API_BASE_URL=""` followed by `ENV VITE_API_BASE_URL=$VITE_API_BASE_URL` did not leave the value unset - it set it to an empty string and overrode .env.production. Nothing about the build says so; it just quietly produces a bundle with no API host. Reproduced directly: building with VITE_API_BASE_URL="" in the environment yields a bundle with no API URL, and building with the variable unset bakes in https://mcp.nearle.ai.in from .env.production. The value now comes from .env.production alone. Point a build elsewhere by editing that file or adding .env.local; both are read by Vite and neither can be silently empty.
