RTCPeerConnectionIceErrorEvent: url property

Baseline 2026

Newly available

Since April 2026, this feature works across the latest devices and browser versions. This feature might not work in older devices or browsers.

The url property of the RTCPeerConnectionIceErrorEvent interface is a string indicating the URL of the STUN or TURN server with which the error occurred.

This example creates a handler for icecandidateerror events, which creates human-readable messages describing the local network interface for the connection and the ICE server used to attempt the connection. It then calls a function to display those messages and the value of the event's errorText property.

pc.addEventListener("icecandidateerror", (event) => {
  const networkInfo = `[Local interface: ${event.address}:${event.port}]`;
  const iceServerInfo = `[ICE server: ${event.url}]`;

  showMessage(event.errorText, iceServerInfo, networkInfo);
});
