  <p>Apparently, the config server is wrong. However, the Spring Cloud Config Server is running at localhost:10000/ and application.yml of the project(config-client) is below. Why the spring.cloud.config.uri doesn't work?</p>
  
  <p><strong>application.yml [config-client]</strong></p>
  
  <pre><code>server:
    port: 10001
  spring:
    application:
      name: config-client
    cloud:
      config:
        label: master
        profile: dev
        uri: http://localhost:10000
  </code></pre>
