Eureka Server has a self-protection mode. When microservices no longer report status to Eureka Server, Eureka Server deletes this service from the service list. If there is a network abnormality (microservices are normal), Eureka server enters the self-protection mode. No longer delete microservices from the service list. It is recommended to turn off the self-protection mode during the development phase.
