在 AWS 中，当安装了特定的 EBS 卷时，我们无法访问 EC2 实例，为什么？

我有一个 EBS 卷，上面有我配置的所有邮件服务器、交换器和 Web 邮件界面。问题是，我们为这个实例创建了一个新子网，因为它需要不同的 EIP。

创建新子网并使用测试实例测试连接后（它起作用了），我们关闭了测试实例，并将连接到旧子网的卷连接到新子网。

实例启动后，我们无法连接到该实例；无法通过 SSH、HTTP、SMTP、IMAP 等方式连接。我将其关闭，并将之前的 EBS 卷重新连接到测试实例，然后就可以正常工作了。

我将 EBS 实例从旧子网重新连接到它之前所连接的实例。现在我们也无法在那里访问它，当我们尝试连接它时，它只是超时。

因此，我构建了一个带有启动卷的新实例，然后将有问题的 EBS 卷安装到 /dev/sdf - 但没有成功。它无法连接。

发生了什么事？为什么当此卷已连接时我无法连接到实例？我该怎么做才能访问该卷并至少恢复我们在那里的一些设置？

谢谢
