🛠️ TROUBLESHOOTING
───────────────────────────────────────────────────────────────────────────────
Backend won't start:
  • Check if port 8000 is free: lsof -i :8000
  • Check Python version: python --version (need 3.11+)
  • Install deps: pip install -r requirements.txt

Frontend won't start:
  • Check Node version: node -v (need 18+)
  • Install deps: npm install
  • Check if port 3000 is free

Can't connect:
  • Ensure both servers are running
  • Check firewall settings
  • Verify .env file in frontend/

No real-time updates:
  • Check browser console for WebSocket errors
  • Verify backend WebSocket is working
  • Check CORS settings

📞 QUICK CHECKS
───────────────────────────────────────────────────────────────────────────────
Is backend running?
  curl http://localhost:8000/health
  # Should return: {"status": "ok"}

Is frontend running?
  Open: http://localhost:3000
  # Should show dashboard

WebSocket working?
  Open browser console, start a scan
  # Should see: WebSocket connected

API working?
  curl http://localhost:8000/api/hosts
  # Should return JSON array
