## Problem CORS error: "Access-Control-Allow-Origin header contains multiple values" caused by both Nginx and NestJS sending CORS headers. ## Solution - NestJS handles CORS exclusively (main.ts) - Nginx acts as SSL proxy only (no CORS headers) - Updated .env.production.example with HTTPS origins - Created GUIA-CORS-PRODUCCION.md with complete documentation ## Files Changed - .gitignore: Allow .env.*.example files - apps/backend/.gitignore: Allow .env.*.example files - apps/backend/.env.production.example: HTTPS CORS config - apps/frontend/.env.production.example: HTTPS/WSS config - docs/95-guias-desarrollo/GUIA-CORS-PRODUCCION.md: Full guide ## Production Steps 1. Update .env.production files with HTTPS origins 2. Remove CORS headers from Nginx config 3. Rebuild frontend, restart backend 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com> |
