The actual nginx config lives at /opt/hotelsync/nginx/conf.d/ (outside git). It used container names (hotelsync-*) not docker-compose service aliases. - cp.hotelsync.ru: hotelsync-frontend:80 → hotelsync-cp:80 - app/guest: restored hotelsync-frontend:80 (was broken by accidental sed) - deploy.yml: added step to sync this file from repo to /opt/hotelsync/nginx/conf.d/ Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
