Cause
No clear root cause identified.
In the controller.log (in HA probe robot) there were so many errors saying
controller probe did not get response from hub probe upon alive check.
Here is an example in controller.log

What was suspected
- local hub (in HA probe robot) was in busy state
- HA probe had issues communicating local hub so it was causing issues for HA probe's heartbeat.
