Minimum required
| Host | Port | Purpose |
|---|---|---|
*.livekit.cloud | TCP 443 | Secure WebSocket signaling |
*.turn.livekit.cloud | TCP 443 | TURN over TLS fallback |
*.host.livekit.cloud | UDP 3478 | TURN/UDP for peer-to-peer |
api.liveavatar.com | TCP 443 | Avatar API and signaling |
Recommended for best performance
- All hosts: UDP 50000–60000 for WebRTC media
- All hosts: TCP 7881 for WebRTC TCP fallback
Tips
- Enable UDP hole-punching where supported
- Avoid symmetric NAT configurations when possible
- UDP is strongly recommended for low-latency performance; TCP fallback degrades quality
Wildcard alternatives
If your firewall doesn’t support wildcards like*.livekit.cloud, consult LiveKit’s firewall documentation using subdomain heygen-feapbkvq.
Troubleshooting
- Browser compatibility test
- Connection tester (requires
