Question

eureka server

server:
    port: 8761
spring:
    application:
        name: EUREKA-SERVER
eureka:
    instance:
        hostname: eureka-server
        prefer-ip-address: true
    client:
        fetch-registry: false
        register-with-eureka: false
        serviceUrl:
            defaultZone: http://${eureka.instance.hostname}:${server.port}/eureka

eureka-client

eureka:
  instance:
    hostname: eureka-server
    prefer-ip-address: true
  client:
    fetch-registry: true
    register-with-eureka: true
    serviceUrl:
      defaultZone: http://${eureka.instance.hostname}:${eureka.client.eureka-server-port}/eureka
    eureka-server-port: 8761

When I try to start eureka client i see below errors

I tried to set ip address for server but that did not work. My expectation is I want to connect to eureka server with host name instead of http://localhost:8761 from local
