Exception: No handle of the given name exists.

This code runs successfully every day, except Saturdays:
param(

    $xmlConfig = "C:\Batch\SFTP_Automation\Config.xml",
    $unrar_path = "C:\Users\USERNAME\AppData\Local\Programs\WinRAR\unrar",

    $FILENAME_File = (Get-Date).adddays(-1).ToString("\MIS_dd")
)

# Set up session options
$sessionOptions = New-Object WinSCP.SessionOptions -Property @{
    Protocol = [WinSCP.Protocol]::Sftp
    HostName = $Config.Configuration.HostIP
    UserName = $Config.Configuration.UserName
    Password = $Config.Configuration.password
    PrivateKeyPassphrase = $Config.Configuration.PassPhrase
    SshHostKeyFingerprint = $Config.Configuration.FingerPrint
    SshPrivateKeyPath = $Config.Configuration.SshPrivateKeyPath
    Timeout = New-TimeSpan -Minutes 10
}
 
$session = New-Object WinSCP.Session
    $session.SessionLogPath = "$LogFilePath\${yyyyMMdd}_SFTP_MIS_Daily_Session.log"
    $session.DebugLogLevel = 2
    $session.DebugLogPath = "$LogFilePath\${yyyyMMdd}_SFTP_MIS_Daily_Debug.log"
 
try
{
    # Connect
    $session.Open($sessionOptions)
    $transferOptions = New-Object WinSCP.TransferOptions
    $session.GetFiles("$RemoteFilePath/MIS_*.exe","$LocalFilePath\MIS_DAILY_${ddMMMyyyy}\",$false,$transferOptions)
}
finally
{
    $session.Dispose()
}

Notice that I have set the timeout to 10 minutes in the $SessionOptions section. This was an attempt to address a timeout error that I am still getting from this transcript:

I have attached a debug log. It looks like it is timing out when reaching out to my XML configuration file. The error shows:
[2023-10-14 09:09:15.071] [000d]   Timeout waiting for WinSCP to respond - asking for callstack

Has anyone had to deal with this before? I am not sure what to do next.

Thank you

Provided successful and failed debug logs

Thank you for your response!
I realized the debug file I uploaded before was for a slightly different process. So I have updated the debug logs, making sure it is consistent with the PowerShell code and transcript I have provided. I have also provided a successful debug log for comparison.

Re: Provided successful and failed debug logs

In the PowerShell script, I put
Timeout = New-TimeSpan -Minutes 10
This was to set the timeout to 10 minutes. May you confirm that I did that correctly? I am having trouble finding examples to make sure.

I suspect the failure is being caused by overload.
Any other tips to make this more resilient? Unfortunately, I am sharing the local server with another IT vendor so the processing may still be an issue going forward.

Re: Provided successful and failed debug logs

In your script, you are setting SessionOption.Timeout.
I was suggesting you to set Session.Timeout:
$session.Timeout = New-TimeSpan -Minutes 10

Re: Provided successful and failed debug logs

Ah! I missed that there was another command. Below is the altered section of the powershell script.
# Set up session options
$sessionOptions = New-Object WinSCP.SessionOptions -Property @{
    Protocol = [WinSCP.Protocol]::Sftp
    HostName = $Config.Configuration.HostIP
    UserName = $Config.Configuration.UserName
    Password = $Config.Configuration.password
    PrivateKeyPassphrase = $Config.Configuration.PassPhrase
    SshHostKeyFingerprint = $Config.Configuration.FingerPrint
    SshPrivateKeyPath = $Config.Configuration.SshPrivateKeyPath
    Timeout = New-TimeSpan -Minutes 10
}
 
$session = New-Object WinSCP.Session
$session.SessionLogPath = "$LogFilePath\${yyyyMMdd}_SFTP_MIS_Daily_Session.log"
$session.DebugLogLevel = 2
$session.DebugLogPath = "$LogFilePath\${yyyyMMdd}_SFTP_MIS_Daily_Debug.log"
$session.Timeout = New-TimeSpan -Minutes 10
Unless there is any other features to add resilience, I'm thinking I will have to keep an eye on it until we deal with the overloading issue.
Thank you for your help!
