There are configured firewall rules to allow health check probes to the
backend.
Misconfigured
There are firewall rules configured to allow partial health check ranges
or block all health check ranges.
If a health check probe is sent from denied IP ranges,
the health check to the backend will fail. Then, the backend will be
marked unhealthy and will not receive traffic sent to the load balancer.
Unspecified
State is unspecified. Default state if not populated.
