Re: Same error

That worked, however, I am still getting sporadic time out issues. I suspect it's due to the RAM limitations. I increased the timeout to 120 seconds. However, it seems the time out exception occurred after a minute or so. Any thoughts? 
SessionOptions sessionOptions = new SessionOptions
{
    Protocol = Protocol.Sftp,
    HostName = "************",
    UserName = "atzzz001",
    Password = "******",
    SshHostKeyFingerprint = "********************",
    Timeout = TimeSpan.FromSeconds(120)
};

Re: WinSCP.SessionRemoteException: Timeout connecting to SFTP

@sreepriya: How exactly do you run the code? Do you really get the problem only "with proxy"? Please attach a full session log file showing the problem (using the latest version of WinSCP).

To generate the session log file, set Session.SessionLogPath. Submit the log with your post as an attachment. Note that passwords and passphrases not stored in the log. You may want to remove other data you consider sensitive though, such as host names, IP addresses, account names or file names (unless they are relevant to the problem). If you do not want to post the log publicly, you can mark the attachment as private.

This is the error (call to log linked files procedure) I am getting. According to this article, (https://winscp.net/eng/docs/message_library_timeout_waiting_to_respond), I supplied the user credentials, but now I am getting
Win32_exception The stub received bad data error.

Googling suggest the process domain is not specified, but I don't see a way to set that.

The task runs under Task Scheduler using a service account. Manually running the task (VS Studio) under my user account seems fine.

Any clues? I have attached the debug log for reference. For this program, there is no file transfer. It only does a directory listing. 
RemoteDirectoryInfo directory = session.ListDirectory("/data");

"Timeout waiting for WinSCP to respond" in Session.open

The Session.open(SessionOptions) is throwing a "Timeout waiting for WinSCP to respond." error when executed in our production server.

The same code works perfectly fine in our Development and local servers.

However, we are able to manually execute the WinSCP.exe GUI and connect to the FTP server in our prod server

Kindly advise if there is anypermission related settings we need to consider.

Did you figure out how come WinSCP was timing out?

Re: Time-Out on session.open

First, why are you setting DisableVersionCheck? Looks suspicious.

Also, please post a callstack of the exception you are getting. I'm not getting it with your code.
paulo_oli

Whole method until this point: 
SessionOptions sessionOptions = new SessionOptions {
    Protocol = Protocol.Sftp,
    HostName = ConfigurationSettings.AppSettings["Host"],
    UserName = ConfigurationSettings.AppSettings["UserName"] ,
    Password = ConfigurationSettings.AppSettings["Pass"] ,
    SshHostKey = ConfigurationSettings.AppSettings["HostKey"] 
};
 
using (Session session = new Session())
{
    // Connect
    session.DisableVersionCheck = true;
    session.Timeout = new TimeSpan(0, 2, 0);
    session.SessionLogPath = @"C:\TEMP\logWinSCP";
    session.ExecutablePath = @"C:\Projetos\tools\WinSCP\WinSCP.exe";
    session.IniFilePath = @"C:\Projetos\tools\WinSCP\WinSCP.ini";
 
    session.DebugLogPath = @"C:\TEMP\logWinSCP";

Hi @martin, how is it going?
After I set Session.DegugLogPath I received the error

Please set Session.DebugLogPath and post or email me the log.

Time-Out on Session.Open

Hi Everybody.
I'm using the component for first time.
I copied the C# example in my class and passed the parameters. When pass by session.Open(sessionOptions), after a long time I get "Time out". Do you have any idea about this waiting time on Session.Open?
