我最近在GCP中挂起了一个VM。几天后，我恢复了它，但我无法以任何方式连接实例。
当ping命令指向外部IP时，我没有得到任何响应。当然，使用网络浏览器发送HTTP请求也不起作用。
如果我尝试使用SSH(使用gcloud或浏览器窗口(进行连接，我会收到连接超时(Putty(或Code: 4003 Reason: failed to connect to backend。我确实尝试再次将SSH公钥编辑显式添加到VM设置中。此外，我有一个用于不同环境的VM，我从未挂起，也没有发布连接。
我检查了防火墙规则，一切似乎都很好。
如果我启用并连接到串行控制台，我会看到它不断记录这些奇怪的消息：

我见过一些SSH出错的线程，但这似乎是引导磁盘的某种错误，或者可能是DHCP配置的错误。
为了防止有人遇到同样的问题，我现在通过在VM上执行RESET操作来解决它。
在花了很长时间试图找到一个合适的解决方案(但没有成功(之后，我认为这将是一个更简单的解决方案，特别是要记住我的VM来自挂起状态。
