Problem Running Poweshell script as Shceduled task

Runs fine if ran from desktop. I have sched task set to run as same user.
I have edited IP and Username for security purposes.

I have found this article but not sure how it applies to using the dll vs the exe "https://winscp.net/eng/docs/faq_scheduler"

****PS Script
$start = Get-Date -format "dd-MMM-yyyy HH mm"
$fileout = "Output.csv"
$logfile = "c:\ConnectScripts\myScript.log"
CD \ConnectScripts


Add-Type -Path "C:\ConnectScripts\WinSCPnet.dll"

try{
# Set up session options
Add-content $logfile -value "Begin FTP"
Add-content $logfile -value "Create Session"
$sessionOptions = New-Object WinSCP.SessionOptions -Property @{
Protocol = [WinSCP.Protocol]::Sftp
HostName = "0.0.0.0"
UserName = "UNAME"
SshHostKeyFingerprint = "ssh-ed25519 256 sBvf50pmJKOpC6pvDBDYbTQOP1PQ2DZhwKDQlFXAUPI="
SshPrivateKeyPath = "C:\ConnectScripts\SCPKEY.ppk"
}

$sessionOptions.AddRawSettings("AgentFwd", "1")
$sessionOptions.AddRawSettings("FSProtocol", "2")

$session = New-Object WinSCP.Session


try
{
$session.SessionLogPath = "C:\ConnectScripts\Session.log"

# Connect
$session.Open($sessionOptions)

# Your code
$session.PutFiles("C:\ConnectScripts\" + $fileout, "/dropoff/*").Check()
}
finally
{
$session.Dispose()
}
}
catch
{
Add-content $logfile -value "Error: $($_.Exception.Message)"
}

**** Exception from Powershell log
Error: Exception calling "Open" with "1" argument(s): "Connection has been unexpectedly closed. Server sent command exit status 0.

That means your .ppk file is actually not a PPK file.
And it "Runs fine if ran from desktop" probably only because you have the matching private key loaded into Pageant (covered in the FAQ you have found).
