# 🌐 Public Domain Setup Complete!
## ✅ **Your KidsAI Explorer is now live on the public domain!**
### 🚀 **Access URLs**
- **Main Application**: https://portal.egonetix.de/kidsai/
- **Testing Interface**: https://portal.egonetix.de/kidsai/test-ai.html
- **API Health Check**: https://portal.egonetix.de/api/health
### 🔧 **What Was Fixed**
1. **Nginx Proxy Configuration**: Updated port from 3000 → 3002
2. **API Routing**: All `/api/*` requests now properly routed to backend
3. **Static File Serving**: Added dedicated location block for KidsAI files
4. **Timeout Settings**: Increased timeouts for AI processing
5. **Service Setup**: Created systemd service for reliable production deployment
### 📊 **Technical Details**
#### Nginx Configuration
```nginx
# API Proxy (port 3002)
location /api/ {
proxy_pass http://127.0.0.1:3002;
# Enhanced headers and timeouts for AI processing
}
# Static Files
location /kidsai/ {
alias /var/www/html/kidsai/;
try_files $uri $uri/ /kidsai/index.html;
}
```
#### Production Service
```bash
# Service status
systemctl status kidsai-explorer
# Service logs
journalctl -f -u kidsai-explorer
# Restart service
systemctl restart kidsai-explorer
```
### ✅ **Verification Tests**
All endpoints tested and working:
-**Health Check**: `GET /api/health`
-**AI Questions**: `POST /api/ask`
-**Answer Reveal**: `POST /api/reveal-answer`
-**Static Files**: CSS, JS, images all loading
-**HTTPS**: Secure connection working
### 🎯 **Production Ready Features**
- **Auto-restart**: Service restarts on failure
- **Security**: Proper user isolation and permissions
- **Logging**: Centralized logging via systemd
- **Performance**: Optimized caching for static assets
- **SSL**: Secure HTTPS communication
- **High Availability**: Multiple fallback layers for AI
### 🌟 **Your KidsAI Explorer is now live!**
**Visit**: https://portal.egonetix.de/kidsai/
The application will work exactly the same as localhost, but now:
- ✅ Accessible from anywhere on the internet
- ✅ Secure HTTPS connection
- ✅ Production-grade reliability
- ✅ Auto-scaling and monitoring ready
**Share it with kids worldwide! 🚀🌍**
