【问题描述】：
所以我从网上启动了我的实例，下载了一个安装它的密钥对，并且一切正常运行了大约一天。然后我重新启动了我的计算机，我无法再通过 SSH 连接它了。我尝试重新下载密钥对并重新安装它，但我不断收到 Permission denied (publickey) 错误。
这是详细的输出（我也尝试过使用 -i /path/to/keypair 选项，但没有成功）：

我也尝试过重启实例。有人有什么我可以尝试的吗？非常感谢！

我会在亚马逊论坛上发布相同的内容：forums.aws.amazon.com/forum.jspa?forumID=30 AWS 员工有一个大多数 SO 用户没有的技巧：他们可以看到发生了什么。 :)
