Following some tutorial on Spring boot microservices using Zuul Netflix Eureka. I have 2 Eureka clients connect to one Eureka server the Zuul proxy is also set up in Eureka server.

I found an issue on github, however, I have gone through my Application.yml configs over and over, just not seeing what I am doing wrong.

All 3 Spring Boot instance is running the same Spring boot version

POM.xml

<parent>

    <groupId>org.springframework.boot</groupId>

    <artifactId>spring-boot-starter-parent</artifactId>

    <version>2.1.0.RELEASE</version>

    <relativePath/> <!-- lookup parent from repository -->

</parent>



<properties>

    ...

    <spring-cloud.version>Greenwich.M1</spring-cloud.version>

</properties>

Eureka Server w/ Zuul proxy config

spring:

  application:

    name: eureka-service



server:

  port: 8302



eureka:

    client:

        registerWithEureka: false

        fetchRegistry: false

        server:

          waitTimeInMsWhenSyncEmpty: 0



zuul:

    #Service will be mapped under the /api URL

    prefix: /api

    routes:

        db-service:

            path: /db-service/**

            url: http://localhost:8300

        stock-service:

            path: /stock-service/**

            url: http://localhost:8301

Eureka clients config

spring:

  application:

    name: stock-service



server:

  port: 8301



eureka:

  client:

    registerWithEureka: true

    fetchRegistry: true

    service-url:

      defaultZone: http://localhost:8302/eureka/

  instance:

    hostname: localhost

My Eureka Dashboard successfully show 2 application registered

I am able to access my REST endpoints through Zuul proxy
http://localhost:8302/api/db-service/rest/db/<name> But I still get these errors.

Questions
1. What am I missing why am I getting these exception?
2. Any suggestions or tools to trouble this...

From the server, as long the server is running I get these following exception in the loop.
