Eureka Server Hangs After few min of Service registration - microservices

Question

I am creating a spring cloud setup. I have Eureka Server, Auth Server, Gateway and two Micro-services. I am using Zuul for Gateway. Below is configuration of Eureka Server:
Main Class
#SpringBootApplication
#EnableEurekaServer
#EnableAdminServer
public class EurekaServerApplication {
public static void main(String[] args) {
SpringApplication.run(EurekaServerApplication.class, args);
}
}
Application properties:
server.port: 8761
spring.application.name: discovery-server

eureka.instance.hostname: localhost
eureka.client.registerWithEureka: false

eureka.client.serviceUrl.defaultZone:

spring.boot.admin.context-path= /admin
Gateway:

#SpringBootApplication
#EnableZuulProxy
#EnableOAuth2Sso

public static void main(String[] args) {
SpringApplication.run(GatewayApplication.class, args);

If any can help me on this, Thanks in advance. :)
All application are working fine individually. But when I start in cluster after service discovery
Eureka Server
hang in few mins.
I get this exception in discovery client:
