# View logs in HuggingFace Space dashboard
# Look for:
✅ "Service Health Monitor Router loaded"
✅ "Technical Indicators Router loaded"  
✅ No 500 errors in comprehensive endpoint
```

---

## 🆘 Troubleshooting

### If Service Health Monitor Shows All Red:
1. Check API keys in HuggingFace Space settings
2. Verify external API services (CoinGecko, Binance) are accessible
3. Check Space logs for connection errors
4. Some services being down is normal - the Space will still function

### If Services Page Still Shows Errors:
1. Verify the commit was pushed successfully
2. Check HuggingFace Space rebuild completed
3. Hard refresh browser (Ctrl+Shift+R)
4. Check browser console for JavaScript errors

### If CSS Animations Still Flicker:
1. Clear browser cache
2. Verify animation-fixes.css is loading (check Network tab)
3. Check for CSS conflicts in browser dev tools
