Значение аннотации не может разрешить заполнитель с удаленного сервера

Сценарий:

Я довольно новичок в Java Spring Boot.Я попытался централизовать конфигурацию на сервере конфигурации облака.Также конфигурация размещена на github.Мой конфиг-сервер настраивается без проблем.Когда я попытался получить значение конфигурации в клиентском приложении, я столкнулся с проблемой.

Ниже описан порядок настройки моего сервера конфигурации:

application.yml (Config Server): 

---
spring:
  application:
    name: client_side
  cloud:
    config:
      server:
        git:
          uri: git@github.com:<user>/Sample-Spring-Boot-Remote-Config.git
          skip-ssl-validation: true
          privateKey: |
            -----BEGIN RSA PRIVATE KEY-----
            -----END RSA PRIVATE KEY-----

---
server:
  port: 8888

И когда я получаю от http://localhost:8888/client_side/default, ответ: 

{
    "name": "client_side",
    "profiles":[
        "default"
    ],
    "label": null,
    "version": "********************",
    "state": null,
    "propertySources":[
        {
            "name": "git@github.com:<user>/Sample-Spring-Boot-Remote-Config.git/client_side.properties",
            "source":{
                "app.mark": "remote"
             }
        }
    ]
}

Я определил app.mark = remote в client_side.properties.Поэтому я думаю, что если я получу этот ответ, это означает, что мой сервер конфигурации работает правильно.

Тогда у меня есть клиентское приложение bootstrap.yml: 

spring:
  application:
    name: client_side
  profiles:
    active: default
  cloud:
    config:
      uri: http://localhost:8888
      enabled: true

application.yml: 

server:
  port: 8910

И мой ClientApplication.java:

package com.example.client;

import org.springframework.beans.factory.annotation.Value;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

@SpringBootApplication
@RestController
public class ClientApplication {

    @Value("${app.mark}")
    private String mark;

    @RequestMapping("/mark")
    public String getMark() {
        return this.mark;
    }

    public static void main(String[] args) {
        SpringApplication.run(ClientApplication.class, args);
    }

}

Когда я попытался запустить свой клиент, я получил трассировку стека ошибок:

Я пытался найтиэта проблема, но ни одно из решений онлайн не работает для меня до сих пор.Также моя весенняя версия в pom.xml: 

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>2.1.4.RELEASE</version>
    <relativePath/> <!-- lookup parent from repository -->
</parent>

<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-dependencies</artifactId>
    <version>${spring-cloud.version}</version>
    <type>pom</type>
    <scope>import</scope>
</dependency>

Я не знаю, почему мой клиент не может подключиться к удаленному серверу.Насколько я понимаю, если я укажу правильный порт, правильную версию приложения и профиля, я смогу получить значение с помощью аннотации @Value.Любая помощь, спасибо заранее.
