2026-06-17T11:17:19.608+05:30 ERROR 7436 --- [Eureka] [get_localhost-5] c.n.e.cluster.ReplicationTaskProcessor : Network level connection to peer localhost; retrying after delay

jakarta.ws.rs.ProcessingException: org.apache.http.conn.HttpHostConnectException: Connect to localhost:8761 [localhost/127.0.0.1, localhost/0:0:0:0:0:0:0:1] failed: Connection refused: getsockopt

i get this log whenever i start a service that tries to register itself with eureka, earlier i thought iwas getting this because of restclient call with wrong config so i changed it to:

@Configuration
@Slf4j
public class RestClientConfig {

    @Bean("loadBalancedBuilder")
    @LoadBalanced
    public RestClient.Builder loadBalancedRestClientBuilder() {
        log.info("LoadBalancedRestClientBuilder");
        return RestClient.builder();
    }

    @Bean("defaultBuilder")
    @Primary
    public RestClient.Builder restClientBuilder() {
        log.info("RestClientBuilder");
        return RestClient.builder();
    }
}

now restclient call works (it uses service name from eureka), kafka works but i also added api-gateway which only work for following config:

              id: user-service
              predicates:
                - Path=/user/**
              uri: http://localhost:8081                               #and not lb://USER-SERVICE

what could be the reason, all service using restclient are already using proper config for restclient so what now?

solved the error, eureka was trying to create replication server and connect with it to sync registery

this is a common behavior of eureka, usually config look like this

spring:
  application:
    name: Eureka
eureka:
  client:
    register-with-eureka: false
    fetch-registry: false

server:
  port: 8080
``` for eureka server

but to avoid replication (only for standalone eureka server), we also need to include:
```yml
eureka:
  service:
    service-url:
      defaultZone: http://localhost:8080/eureka/
``` this stops eureka from finding connection to sync registery
