  <p>The microservice keeps trying to connect to the server every 10sec, but fails. What may be the cause for this?</p>
  
  <p>Microservice(client) application.yml is as following:</p>
  
  <pre><code>spring:
    application:
      name: Product
  server:
    port: 9090
  
  eureka:
    client:
      serviceUrl:
        defaultZone: http://localhost:8761/eureka/
  </code></pre>
