No Downloads Required

• Everything runs directly in the supported web browser.

Network & Internet Requirements

Reliable network connectivity is critical for a successful RON session.

Recommended Internet Speeds

• Minimum:
  • 3 Mbps download / 2 Mbps upload
• Recommended:
  • 10 Mbps download / 5 Mbps upload or higher for best audio/video quality

Connection Type

• Wired Ethernet: Recommended for notaries hosting sessions
• Wi-Fi: Supported but should be stable with strong signal strength
• Avoid using mobile hotspots or public Wi-Fi networks when possible.

Firewall & Security Considerations

• Your network or IT department must allow:
  • Standard HTTPS traffic (port 443)
  • WebRTC or similar real-time communication services used for audio/video
• Corporate networks with strict firewalls, VPNs, or content filters may need to whitelist the platform’s domain(s).

Unsupported Environments

The following setups are not supported and may cause failures:

• Outdated browsers or unsupported browser versions
• Internet Explorer or legacy browsers
• In-app browsers embedded in email, messaging, or social apps
• Devices without webcams or microphones
• Joining from a locked-down corporate network that blocks real-time video traffic
• Very slow or unstable internet connections

Best Practices for a Successful Session

• Close unnecessary browser tabs and applications to improve performance.
• Test your camera and microphone before the session.
• Ensure your device’s date and time are correct (incorrect system time can cause security or SSL issues).
• Use a quiet, well-lit environment so the notary can clearly see and hear you.
