How to upload via FTP to Powershell, behind a proxy?

Question

I am trying to use FTP in Powershell to upload a file. I use FtpWebRequestlater and then GetRequestStream, but this method returns an error:

"The requested FTP command is not supported when using the HTTP proxy."

I really am for the proxy and should be.

How can I load through Powershell when behind a proxy?

This will only be done with a .ps1Powershell script.

I also tried:

$webclient = New-Object System.Net.WebClient
$uri = New-Object System.Uri($server)

$webclient.UploadFile($uri, "C:\Test\1234567.txt")

Where $serverand this file are valid. But this code returns this error:

"An exception occurred during a WebClient request."
At C:\Test\script.ps1:101 char:26
+     $webclient.UploadFile <<<< ($uri, "C:\Test\1234567.txt")
    + CategoryInfo          : NotSpecified: (:) [], MethodInvocationException
    + FullyQualifiedErrorId : DotNetMethodException

I also tried double backslash in files, didn't help.

The proxy I'm connected to applies only to HTTP, not FTP.
