title: Spring boot admin shows status of gateway server down
body: <p>I develop a micro services environment.It is developed by the spring cloud.</p>
  
  <p>The gateway server has been developed by the Zuul and has secured by X.509 certificate authentication(mutual authentication).</p>
  
  <p>I use spring boot admin for monitoring the micro services.</p>
  
  <p>I already use Spring Cloud Discovery for my applications and i added a DiscoveryClient to Spring Boot Admin Server:</p>
  
  <pre><code>@Configuration
  @EnableAutoConfiguration
  @EnableDiscoveryClient
  @EnableAdminServer
  public class ApiAdminServerApplication {
  
      public static void main(String[] args) {
          SpringApplication.run(ApiAdminServerApplication.class, args);
      }
  }
  </code></pre>
  
  <p>Spring boot admin properties:</p>
  
  <pre><code>management.endpoints.web.exposure.include=*
  management.endpoint.health.show-details=ALWAYS
  spring.security.user.name=admin
  spring.security.user.password=password
  </code></pre>
  
  <p>Service discovery properties:</p>
  
  <pre><code>management.endpoint.metrics.enabled=true
  management.endpoints.web.exposure.include=*
  management.endpoint.prometheus.enabled=true
  management.metrics.export.prometheus.enabled=true
  management.metrics.tags.application=${spring.application.name}
  </code></pre>
  
  <p>Gateway properties:</p>
  
  <pre><code>server.ssl.enabled=true
  server.ssl.key-store-type=PKCS12
  server.ssl.key-store=classpath:tls/keyStore.p12
  server.ssl.key-store-password=changeit
  server.ssl.trust-store=classpath:tls/trustStore.jks
  server.ssl.trust-store-password=changeit
  server.ssl.trust-store-type=JKS
  server.ssl.client-auth=need
  </code></pre>
  
  <p>The gateway server is shown in spring boot admin panel as an application but its status is down.</p>
  
  <p>How do I config spring boot admin for monitoring https gateway application?</p>
