After the api container restarts it gets a new IP; nginx cached the old one at startup and kept proxying /api/* to the stale address — which by then belonged to another service (casdoor), so login returned Casdoor's error envelope and the frontend crashed with "Cannot read properties of null (reading 'user')". proxy_pass now uses a variable + resolver 127.0.0.11 so the upstream re-resolves per request. Verified: login works, and still works after restarting the api container.
