When docker compose recreates a service, it gets a new internal IP. nginx was resolving upstream hostnames once at startup and serving 502 until someone manually restarted it — which is what broke /api/auth after the last deploy. Uses Docker Compose's embedded DNS (127.0.0.11) and moves each proxy_pass onto a variable so nginx re-resolves every request. Rewrites replace the path-stripping behavior that variable-form proxy_pass doesn't provide out of the box. Also adds a `nginx -t && nginx -s reload` step in the deploy workflow so future nginx.conf edits land without manual ssh. Co-authored-by: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
