Why isn't no data status being displayed for the IP endpoint?

In case the probe doesn't transmit no data for the configured IP, the status will not display no data, and this will be indicated in the "Network QOS" section of the specific IP Endpoint when you navigate to "IP Endpoints > All IP Endpoints" and click on it. You can observe the absence of data in the availability timeline.
