With a variable upstream ($ui_upstream, added for docker-DNS re-resolution), a trailing-slash URI in proxy_pass makes nginx forward '/' to the UI for every sub-path, so /_next/static/*.css and /i/<invoice> all return the app index HTML (200 text/html) -> the UI renders unstyled and client routing breaks. Omit the URI to preserve the full request path, matching the /api/ block.

# Docker's embedded DNS (127.0.0.11) lets nginx re-resolve upstream service
|
|
# hostnames. Without `resolver` + a variable-based proxy_pass, nginx resolves
|
|
# `api` / `ui` to an IP once at startup and caches it forever — if the api
|
|
# container is rebuilt and Docker gives it a new IP, nginx keeps hitting the
|
|
# old one and every request returns 502 Bad Gateway until nginx is manually
|
|
# restarted. `valid=10s` bounds the stale window to ~10 seconds.
