Remarks

This event fires anytime a client has unregistered itself from further notifications for the resource identified by URI. Refer to the start_observing and send_notification methods, as well as the on_notification and on_register events, for more information about observing resources and resource change notifications.

The RemoteHost parameter reflects the client's IP address or hostname.

The RemotePort parameter reflects the client's port.

The URI parameter identifies the resource that the client has stopped observing.

The URIHost, URIPort, URIPath, and URIQuery parameters are provided for additional convenience

Note: This event is only used when the class is operating in server mode (i.e., when the listening property is enabled).
