Hey everyone, happy new year!
Somehow I keep getting sensor status DOWN (The RPC server is unavailable), but is totally random. Sensor shows good, and change to bad, back to good, and back to bad. Only one sensor, the others sensors it's OK.
PRTG shows sensor is down, but when try WMI tester it's all good.

This issue happens to any server and any sensor, is totally random
