Zuul cannot connect to Eureka - spring-cloud

Question

I have a Eureka server running ok and a service connecting to it.
Now, I'm trying to connect a Zuul server to Eureka, but it isn't working.
I configure Zuul like this:
zuul:
ignoredServices: "*"
routes:
contacts-service:
path: /contacts/**
serviceId: contacts-service
eureka:
instance:
preferIpAddress: true
client:
serviceUrl:
defaultZone: http://eureka:admin#127.0.0.1:8761/eureka/
and my class as
#SpringBootApplication
#EnableZuulServer
#EnableDiscoveryClient
public class EdgeApplication {
public static void main(String[] args) {
SpringApplication.run(EdgeApplication.class, args);
}
}
It never show in eureka neither nothing on the zuul logs eureka-related. Seems like I'm still missing something.
Edit
When I changed to #EnableZuulProxy, I get an error and the zuul service is still not shown at Eureka server

From time to time, I see this in the eureka server logs (not sure if its related or not to my problem, tho):

and right after I call the `/contacts/ endpoint, I see this in the zuul proxy logs:

Answer 1

You are missing following dependency in your zuul service:
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-eureka</artifactId>
</dependency>

Answer 2

I used this below which works for me.
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
</dependency>
