"Load balancer does not have available server for client". Is this a bug or my config was wrong?

[1011178l]

I noticed that many people asked the same question, But I tried their ways, but my problem is still there.

I use spring-boot + eureka + zuul,

spring.cloud.version: 2.0.2.RELEASE

Here is the Eureka server:

@SpringBootApplication
@EnableEurekaServer
@Slf4j
public class EurekaServerApplication {

    public static void main(String[] args) {
        SpringApplication.run(EurekaServerApplication.class, args);
        log.info("-- EurekaServerApplication started --");
    }
}

and the application.yml for eureka server:

server:
port: 8888

eureka:
  client:
    registerWithEureka: false
    fetchRegistry: false
    healthcheck:
      enabled: true
    service-url:
      defaultZone: http://localhost:8888/eureka

Then here is the Zuul server:

@SpringBootApplication
@EnableZuulProxy
@EnableEurekaClient
@Slf4j
public class ZuulServerApplication{

    public static void main(String[] args) {
        SpringApplication.run(ZuulServerApplication.class, args);
        log.info("-- ZuulServerApplication started --");
    }
}

and the application.yml for Zuul

server:
  port: 7777

eureka:
  instance:
    appname: zuul-server
  client:
    serviceUrl:
    defaultZone: http://localhost:8888/eureka

zuul:
  ignoredServices: '*'
  routes:
    file-management:
      path: /file-management/**
      serviceId: file-management

and a microservice file-management:

@SpringBootApplication
@EnableEurekaClient
@EnableSwagger2
@Slf4j
public class FileManagementApplication {
    public static void main(String[] args) {
        SpringApplication.run(FileManagementApplication.class, args);
        log.info("-- FileManagement started --");
    }
}

application.yml

... some other configs
server:
  port: 8081
eureka:
  instance:
    appname: file-management
  client:
    serviceUrl:
    defaultZone: http://localhost:8888/eureka

I have this problem for a couple of days, Any help would be great appreciated!

After I did a basic debug, I find the allServerList in the class BaseLoadBalancer is null. Not sure if this info is useful.

for your zuul application.yml fetch the registry as below

eureka:
  client:
    registerWithEureka: false
    fetchRegistry: true

@senyoAsamoah Thanks. Can I manully define route rather than use fetchRegistry?

[senyoAsamoah]

You can manually define, just use the url field in the routes definition for zuul

hi,I have the same question to yours.do you haven solved it ,please?

[Luolanjiao]

I got it ! you could check out your maven file that must imput the "spring-cloud-starter-netflix-eureka-client",not the "spring-cloud-netflix-eureka-client".because the "spring-cloud-starter-netflix-eureka-client" include ribbon-eureka,but the other one is not . with ribbon-eureka ,it can do the balance.^_^

[JohnneSouza]

for your zuul application.yml fetch the registry as below

eureka:
  client:
    registerWithEureka: false
    fetchRegistry: true

That solved my problem.

[frangel02]

Configurations Basic Eureka Client

only set this -> eureka.client.enabled=false in the microservice That solved my problem.

[tan-i-ham]

for your zuul application.yml fetch the registry as below

eureka:
  client:
    registerWithEureka: false
    fetchRegistry: true

this solved my problem, too.
