通常，我们可以使用 Azure Service Fabric DNS 通过服务名称 ping 另一个服务。昨晚凌晨1点左右，这停止了工作。没有更改任何代码或配置，也没有部署任何内容。现在，在一个容器中，我们无法 ping 另一个服务：
一些信息：我们在 Azure 中运行 Service Fabric 并运行 Windows 集群。我们所有的服务都在 Docker 容器中运行，使用 Docker for Windows。
我们尝试过的事情：重新启动虚拟机，删除并重新部署所有应用程序，重新启动集群中的命名服务和 DNS 服务。
有人见过这样的吗？我正在寻找有关可能出现问题的提示，或有关如何进一步调试此问题的提示。同样，没有部署任何内容，也没有更改任何代码或配置。似乎 Service Fabric 的内部 DNS 突然出现故障，并且不会再次出现。谢谢！
