在Google Compute Engine中重新启动后无法连接

由于过度使用，我不得不升级我的机器，导致重新启动。 之后，我无法通过PuTTY连接，只能使用Google控制台。

此外，我的SVN存储库在那里，我也无法连接到它。

我查看了“VPC Network”中的防火墙规则，在重启前它们是一样的：

• 在Google Compute Engine上运行Google App Engine
• 我可以在Google Compute Engine实例中使用SQL Server吗？
• 在GCE中使用StackDriver监控MongoDB 3
• 如何在Google Cloud（Google Compute Engine）上安装驱动器？
• 'BUG：无法在Google Compute Engine上处理内核NULL指针解除引用

iptables -L的输出：

我的SSH密钥仍然在.ssh/authorized_keys但是在使用PuTTY时，即使在询问用户之前，它也会死亡：

 Network error: connection timeout 

当试图更新我的SVN本地副本它死了“因为主机没有回应”。

我已经看了：

• 这和这不解决问题，因为我使用谷歌控制台访问完美
• 这也不是，因为它涉及到第一次连接的问题
