Spring Boot 无法使用Eureka 从API网关连接到微服务

我创建了一个微服务环境，包括一个用户微服务、一个API网关、Eureka 和Rabbitmq。
然后，我将每个镜像都对接起来，并在它们自己的EC2示例上运行这些镜像。
一切正常，服务在Eureka 中注册，正确连接到rabbit服务器并可以使用云配置。此外，配置入站规则，以便微服务可以相互连接。
当我只使用用户微服务发送请求来创建用户或登录用户时，它可以正常工作。
问题是，当我使用网关API来使用用户微服务时，我会得到这个错误：

字符串
我觉得奇怪的是，它说连接拒绝：/172.17.0.2：8181这让我很困惑，因为如果我正确地发出请求，我应该将请求发送到{ms-aws-ip}：8181
Also, I noticed a difference between the tutorial I am following and what I see on my Eureka screen我看到正在执行教程的人可以看到到Eureka 中aws示例的客户端链接，其格式为ip-xx. xx. xx.xx.ec2.internal：users：8181
这些是微服务的application.properties，它们的配置运行在localhost上。在运行Docker镜像时，我更改了配置，以便它们可以相互连接。
Eureka ：

我尝试将此添加到微服务中，但不起作用：Eureka .instance.preferIpAddress=true
