无法从 docker 容器写入 AWS ClouldWatch

Question

我在Windows容器中运行一个.net核心应用程序，它使用AWS SDK连接到ClouldWatch。我使用Serilog.Sink.AWSCloudWatch进行此集成。

当我从主机运行它时，CloudWatch 集成可以正常工作，但是当我从 Windows docker 容器尝试时，我遇到了以下异常。由于我是码头工人的新手，您能帮助我解决这个问题吗？

Error initializing log stream. No logs will be sent to AWS CloudWatch. Exception was System.Net.Http.HttpRequestException: No such host is known.

实际问题是我在打开 vpn 的情况下运行应用程序，因此 https 请求被 vpn 拒绝。我设法在没有 vpn 的情况下解决了这个问题。
