RTCPeerConnection.onicecandidateerror

The RTCPeerConnection.onicecandidateerror property is an event handler which specifies a function which is called to handle the icecandidateerror event when it occurs on an RTCPeerConnection instance. This event is fired when an error occurs during the ICE candidate gathering process.

Syntax

RTCPeerConnection.onicecandidateerror = eventHandler;

Value

This should be set to a function you provide which is passed a single parameter: an RTCPeerConnectionIceErrorEvent object describing the icecandidateerror event. The event offers properties describing the error to help you handle it appropriately.

Example

pc.onicecandidateerror = function(event) {
  if (event.errorCode >= 300 && event.errorCode <= 699) {
    // STUN errors are in the range 300-699. See RFC 5389, section 15.6
    // for a list of codes. TURN adds a few more error codes; see
    // RFC 5766, section 15 for details.
  } else if (event.errorCode >= 700 && event.errorCode <= 799) {
    // Server could not be reached; a specific error number is
    // provided but these are not yet specified.
  }
}
