spring Boot /微服务和Eureka 存在问题

我在intellij中运行了2个spring Boot /microservices。这两个服务启动时都没有错误。但如果第一个microservice尝试从第二个microservice调用服务，我会收到错误。有什么想法吗？代码在测试环境中运行良好，但在我的本地计算机上，我收到了下面的错误。我不知道应该从哪里开始查找错误。这两个microservices都在Eureka 注册，状态为“UP”。如果我把异常中显示的URL复制到浏览器，我不会得到连接超时。所以我认为问题出在intellij的某个地方，但我不知道哪里有东西可以“阻止”我的请求。我使用的是openjdk 8。任何提示都很好，谢谢

很难说出到底是什么问题，如果你能提供更多的配置信息，那就更好了。因为这是一个连接超时错误，我建议在www.example.com中设置faign超时application.properties:

feign.client.config.default.connectTimeout: 160000000

找到了窃听器...

-Djava.net.preferIPv4Stack=true

在VM选项...没有这个设置，它工作得很好。
