Tips to ensure a successful connection
- If your network has restrictive filtering, whitelist your SmartBox's MAC address.
- Your SmartBox needs to be able to connect to Cloudflare's DNS servers (1.1.1.1, 1.0.0.1).
- Your SmartBox needs to be able to contact 4 services running on different subdomains of keycafe.com (subdomain.keycafe.com):
| Subdomain | Port | Service |
| push | 500 | Push notifications |
| monitor | 443 | Device monitoring |
| ota | 443 | Over-the-air updates |
| www | 443 | General functionality |
IP Address Whitelisting
The IP addresses used by Keycafe for cloud services are subject to change, so we recommend not relying on a static whitelist.
