WebRTC Test
Verifies that this workstation can complete a WebRTC connection. If this passes, Zoom, Teams, Slack Huddles, Google Meet, and similar apps should be able to connect.
Read the WebRTC Test guide for help reading the verdict or fixing each failure mode.
Privacy: This test creates two RTCPeerConnections inside this browser tab and queries public STUN endpoints to discover ICE candidates. It does NOT request camera or microphone access. Your local IP and public IP are visible to this page (that is the point of step 2) but are not transmitted anywhere. View source to verify.
