title: Spring Boot Microservice cant connect to Eureka Server
body: <p>I try to connect my service (auth-service) to the Eureka Server for the service registry. The Eureka server is running, but when I try to connect the auth-service nothing happens.</p>
  
  <p>I added the configurations to application.yaml and application.properties, but nothing helped.</p>
  
  <p>application.yaml from auth-service:</p>
  
  <pre><code>eureka:
        client:
          fetchRegistry: true
          registryFetchIntervalSeconds: 5
          serviceUrl:
            defaultZone: http://localhost:8761/eureka
        instance:
          preferIpAddress: true
  </code></pre>
  
  <p>URL of Eureka server: <a href="http://localhost:8761/" rel="nofollow noreferrer">http://localhost:8761/</a></p>
  
  <p>DS Replicas: localhost</p>
  
  <p>Message when I start auth-service:</p>
  
  <pre><code>2019-05-24 16:58:11.457  INFO [auth-service,,,] 14704 --- [           main] o.s.s.concurrent.ThreadPoolTaskExecutor  : Initializing ExecutorService 'applicationTaskExecutor'
