Spring Boot Admin client status is down - spring

Question

I have a SpringAdminServer(1.5.0), an EurekaServer, and an EurekaClient.
The SpringAdminServer uses #EnableDiscoveryClient way to host. I can see both SpringAdminServer and EurekaClient registering to EurekaServer normally. However, the status of EurekaClient shown on SpringAdminServer is always "DOWN".(SpringAdminServer show 404 error to requesting EurekaClient's /info or /metric path...)
I tried another way of including spring-boot-admin-starter-client into the client's POM, which will make the client's status UP on the SpringAdminServer and thus no errors found to request the /info or /metric path...
Anyone knows what happened? Thanks.
Here are the content of my client's POM:

ADD
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-actuator</artifactId>
</dependency>
to POM will do the trick.
