This article outlines the required network settings for EloView 4 devices to operate in the production environment. Please ensure the following domains, URLs, ports, and services are accessible.
Required EloView 4 Domains
| URL | Purpose |
|---|---|
https://secure-api.eloview.com/prod | Token API / OTA updates / OS360 warranty checks (outgoing) |
https://secure-provisioning.eloview.com/prod | Provisioning base URL (outgoing) |
https://secure-broker.eloview.com | MQTT Broker URL |
https://secure-logs.eloview.com | Upload logs / OTA builds / private content (outgoing & incoming) |
https://secure-content.eloview.com | Content icons on device |
https://secure-auth.eloview.com | OAuth login by device |
https://polaris-prod-public-ota.s3.us-west-2.amazonaws.com/systemUpdate/ | For custom OTAs |
| https://secure.eloview.com/systemUpdate/ | System updates |
Additional Required URLs
*.1e100.net→ Google-owned domain used by various APIs and cloud services*.us-west-2.compute.amazonaws.com→ AWS IoT Core and Lambda serviceshttps://cognito-identity.us-west-2.amazonaws.com/https://cognito-idp.us-west-2.amazonaws.com/https://polaris-promote-prod.s3.us-west-2.amazonaws.comhttps://polaris-scan-prod.s3.us-west-2.amazonaws.comeloprod.blob.core.windows.net(Azure Blob Storage)
Optional Services
TeamViewer (if required)
*.teamviewer.com
Time Synchronization (NTP)
*.pool.ntp.orgtime.android.com2.android.pool.ntp.orgtime.google.com
Note: EloView uses
2.android.pool.ntp.orgfor NTP traffic. Full access to port 123 (UDP) is required.
⚠️ Caution: A fresh device may initially be out of sync with the system time. In such cases, the device must connect to the Android specific NTP server to establish successful communication with EloView. This initial connection is required to retrieve the necessary EloView configurations, including intranet NTP server details.
Cloudflare CDN
EloView services rely on Cloudflare’s global content delivery network (CDN).
Recommendation: Always whitelist by domain name (e.g., the EloView domains listed above).
Why: Cloudflare IP addresses are dynamic and subject to change. IP whitelisting can cause unexpected service interruptions if ranges are updated.
Reference only: If your firewall requires explicit IPs, the following are currently in use:
IPv4 (sample set):104.16.60.227, 104.16.61.227, 104.16.62.227, 104.16.63.227, 104.16.64.227
IPv6 (sample set):2606:4700::6810:3ce3, 2606:4700::6810:3de3, 2606:4700::6810:3ee3, 2606:4700::6810:3fe3, 2606:4700::6810:40e3
Required Ports & Protocols
443 (HTTPS): General EloView communication
8883 (MQTT over TLS): Secure device-to-cloud communication
123 (UDP – NTP): Time synchronization
Note: EloView-enabled Android devices use WebSocket connections. Communication is always device-initiated.
✅ Summary:
For EloView 4 devices to function correctly, whitelist the EloView domains, allow the additional supporting URLs, ensure the required ports are open, and allow NTP synchronization. Always use domain-based rules instead of IPs to prevent service disruptions.
