[quote="junpei.liang@gmail.com"]I wrote a power script to download the FTP file to the local machine automatically. 
Often I got the transfer channel can't be opened error. Can you please help?

[code]@powershell@
try {
    Add-Type -Path "C:\Program Files (x86)\WinSCP\WinSCPnet.dll"

try {
        $sessionOptions = New-Object WinSCP.SessionOptions -Property @{
            Protocol = [WinSCP.Protocol]::ftp
            HostName = $remoteHostName
            UserName = $remoteUsername
            Password = $remotePassword
            Timeout  = New-TimeSpan -Minutes 5
            #SshHostKeyFingerprint = "ssh-rsa 2048 xxxxxxxxxxx...="
        }
        
        # Force IP address for passive mode connections
        # https://winscp.net/eng/docs/rawsettings
        $sessionOptions.AddRawSettings("FtpForcePasvIp2", 0)

$session = New-Object WinSCP.Session
        #$session.ExecutablePath = "C:\Program Files (x86)\WinSCP\WinSCP.exe"
        $session.SessionLogPath = $winscpLogFilePath
        writeToLog ("Connecting to $($remoteHostName)!")
        $session.Open($sessionOptions)

if ($session.FileExists($remoteFilePath)) {
 writeToLog ("File $($remoteFileName) presented in $($remoteHostName) $($remoteFolderPath)!")
 $reportHTMLMessage += "<td>Available</td>" 
 try {
 $session.GetFiles($remoteFilePath, $downloadFolderPath).Check() 
 }
 catch {
 $getFileError = $true
 throw $_
 } 
 }
 else {
 writeToLog ("File $($remoteFileName) not presented in $($remoteHostName) $($remoteFolderPath)!")
 $reportHTMLMessage += "<td>Missing</td>"
 }
 }
 catch {
 writeToLog ($_ | Out-String)
 $statusDescription = removeNewlineChar(($_.Exception.Message).toString())
 $reportHTMLMessage += "<td>$($statusDescription)</td>"
 }
 finally {
 $session.Dispose()
 }
}
catch {
 writeToLog ($_ | Out-String)
 $statusDescription = removeNewlineChar(($_.Exception.Message).toString())
 $reportHTMLMessage += "<td>$($statusDescription)</td>"

Transfer channel can't be opened

I wrote a power script to download the FTP file to the local machine automatically.
Often I got the transfer channel can't be opened error. Can you please help?
