How to get filename returned by a download link?

When requesting https://aka.ms/win32-x64-user-stable in browser, it returns this filename "VSCodeUserSetup-x64-1.27.2.exe" to be saved.

I want to get this same info "VSCodeUserSetup-x64-1.27.2.exe" so I tried:

$webRequest = [net.WebRequest]::Create("https://aka.ms/win32-x64-user-stable")
$test = $webrequest.GetResponse()

But I'm getting error:

Exception calling "GetResponse" with "0" argument(s): "The underlying connection was closed: An unexpected error occurred on a send."

Is it the right method or what else ?

I don't understand why because I followed https://learn-powershell.net/2011/02/11/using-powershell-to-query-web-site-information/ and there is no arg given for GetResponse.

I can reproduce the problem by doing the following:

[Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls11
$webRequest = [net.WebRequest]::Create("https://aka.ms/win32-x64-user-stable")
$test = $webrequest.GetResponse()

So it stands to reason this is a TLS issue. You can check the TLS version by running:

[Net.ServicePointManager]::SecurityProtocol

and if appropriate, try setting the TLS version as follows:

[Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls12
$webRequest = [net.WebRequest]::Create("https://aka.ms/win32-x64-user-stable")
$test = $webrequest.GetResponse()

Example (TLS 1.1):

[Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls11
Write-host "TLS Version: $([Net.ServicePointManager]::SecurityProtocol)"
$webRequest = [net.WebRequest]::Create("https://aka.ms/win32-x64-user-stable")
$webRequest.GetResponse()

TLS Version: Tls11
