ubuntu - 在谷歌云平台上连接 ssh 时出错

Question

我的实例在 Google Cloud Platform 上运行，但突然我的网站停止工作，当我尝试通过 SSH 登录时，它保持连接而不是永远连接。它说:
向项目元数据的 key 传输花费了异常长的时间。相反，传输到实例元数据可能会更快，但只会将 key 传输到此 VM。如果您希望从该虚拟机通过 SSH 连接到其他虚拟机，则需要相应地传输 key 。单击此处将 key 传输到实例元数据。请注意，此设置是持久的，一旦启用，需要在“实例详细信息”页面中禁用。通过迁移到 OS Login，您可以显着缩短 key 传输时间。
当我检查元数据时，它显示异常事件，其中显示:

google-ssh {"userName":"XXXXXXX@XXXX.com","expireOn":"2021-09-24T10:12:18+0000"}
