c.n.d.s.t.d.RedirectingEurekaHttpClient : Request execution error - Connection refused while trying to register eureka-clients

Hi,

I was trying to register eureka clients with Eureka server using springboot application module as a client.

I was getting below error:

Solution:

Not sure, what is the issue with application.properties. removed properties file and added application.yml file. Now, error gone.

application.properties:

spring.application.name=products-crawler

server.port=9001

#Eureka server client

eureka.client.register-with-eureka=true

eureka.client.fetch-registry=true

eureka.client.service-url.default-zone = http://127.0.0.1:9002/eureka/

eureka.instance.hostname=localhost

application.yml

spring:

  application:

    name: products-crawler

server:

  port: 9001

eureka:

  client:

    registerWithEureka: true

    fetchRegistry: true

    serviceUrl:

      defaultZone: http://127.0.0.1:9002/eureka/

  instance:

    hostname: localhost
