CORS errors in browser

Verify frontend URL in CORS_ORIGINS environment variable
Restart backend after .env changes
Clear browser cache: Ctrl+Shift+Delete
Check CORS headers: curl -I http://localhost:8000/health

Login not working

Verify database created: psql -lqt | grep cogniflow
Run migrations: python -m alembic upgrade head
Check JWT_SECRET configured in .env
Verify Redis running for rate limiter

Embeddings not generating

Verify OPENAI_API_KEY or other provider key set
Check EMBEDDING_PROVIDER in .env
Verify Redis connection for batch queue
Check Celery worker running: ps aux | grep celery

Vector search not working

Verify Qdrant running: curl http://localhost:6333
