[英]PuTTy Connection timed out for EC2
I created Ubuntu instance in EC2. 我在EC2中创建了Ubuntu实例。 And worked fine so far.
到目前为止工作还不错。
But somehow I can't connect to the server by PuTTy anymore and I get Network error: Connection timed out
. 但是由于某种原因,我无法再通过PuTTy连接到服务器,并且出现
Network error: Connection timed out
。

A Connection timeout is a sign that your computer is unable reach the remote computer. 连接超时表示您的计算机无法访问远程计算机。 Such an error normally takes some time before it fails.

。
