Cluster Sensor Probe Health: Disconnected



We have two servers in cluster. Cluster communication operates normally but on Sensor Probe Health (Cluster Probe Device) I can see Last Message: Disconnected on both servers. The Sensor has green color but this message is alarming. Should I be concerned or is it normal?
