Spring Cloud Netflix /actuator/readiness is OUT_OF_SERVICE，eureka-server status is UP?

AvailabilityChangeEvent.publish(applicationContext, ReadinessState.REFUSING_TRAFFIC);

When this method is called manually， localhost:8080/actuator/health status is OUT_OF_SERVICE, localhost:8080/actuator/health/liveness status is UP, localhost:8080/actuator/health/readiness status is OUT_OF_SERVICE,

At this time，Check the status of this service in the eureka-server background, which is always UP?
