无法从EC2 Windows Machin中的Powershell获取实例ID

Question

I can able to get the instance-id from AWS EC2 windows machine's IE browser using the URL http://169.254.169.254/latest/meta-data/instance-id

In the same machine when I use Powershell command

Invoke-WebRequest http://169.254.169.254/latest/meta-data/instance-id

then I am getting below error

Invoke-WebRequest : Network Error (tcp_error) A communication error occurred: "Operation timed out" The Web Server may be down, too busy, or experiencing other problems preventing it from responding to requests. You may wish to try again at a later time. For assistance, contact your network support team. At line:1 char:1
+ Invoke-WebRequest http://169.254.169.254/latest/meta-data/instance-id
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

    + FullyQualifiedErrorId : WebCmdletWebResponseException,Microsoft.PowerShell.Commands.InvokeWebRequestCommand

Note: Invoke-WebRequest http://google.com is working and giving the response from PowerShell cmd.

Please anyone clarify what is this error.

What exactly does this need to do? Download data from the URL? I've never seen such a think before, but I would THINK you could use the System.Web.Uri class to do it, like so:

$var = New-Object System.Web.Uri
$var.Download("http://169.254.169.154/latest/meta-data/instance-id")

Does something like that work?
