I have Eureka Server and Client in my application. When I am trying to Start clients Eureka Server stop responding and I get this log :

Below is the client and Server Config:
Client Main Class:
@SpringBootApplication
@EnableAutoConfiguration
@EnableDiscoveryClient
@EnableHypermediaSupport(type = EnableHypermediaSupport.HypermediaType.HAL)
@EnableFeignClients
public class NyotaPlateformApplication {
public static void main(String[] args) {
SpringApplication.run(NyotaPlateformApplication.class, args);
}
}
application.properties client :
server.port= ${PORT:4445}
spring.application.name= nyota-plateform
spring.main.banner-mode=off
security.oauth2.resource.user-info-uri= http://localhost:8999/user
eureka.client.serviceUrl.defaultZone= http://localhost:8761/eureka/
Server Main Class:
@SpringBootApplication
@EnableEurekaServer
public class EurekaServerApplication {
public static void main(String[] args) {
SpringApplication.run(EurekaServerApplication.class, args);
}
}
Application properties:
server.port: 8761
spring.application.name: discovery-server
logging.level.org.springframework.cloud.netflix.eureka: TRACE
eureka.instance.hostname: localhost
eureka.client.registerWithEureka: false
eureka.client.fetchRegistry: false
eureka.client.serviceUrl.defaultZone: http://${eureka.instance.hostname}:${server.port}/eureka/
Other clients have same configuration. When I start only eureka Server it works fine and after starting more than 1 client it stops responding. After sometime I get following error on client side:
DiscoveryClient_FSP-MARKETPLACE/192.168.3.180:fsp-marketplace:4444 - was unable to refresh its cache! status = Cannot execute request on any known server

What could be the reason?
