Winscp assembly getting timeout

Hi folks,

I had set these setting
sessionOptions.Timeout = new TimeSpan(0,2, 0);
if (session.Opened == false) {
session.Open(sessionOptions);
session.Timeout = new TimeSpan(0, 3, 0);
}

but still i am hit with this timeout error.
System.NullReferenceException: Object reference not set to an instance of an object. at WinSCP.Session.CheckForTimeout(String additional) at WinSCP.Session.Open(SessionOptions sessionOptions)


from the winscp log below, it seem to get this timeout error after 60sec.

Re: Winscp assembly getting timeout

Session.Timeout has to be set before Session.Open. Though I do not think it would help anyway.

In what environment are you running your code? What version of WinSCP? Please attach a complete WinSCP .NET assembly debug log file.

Thanks. Though you did not answer "In what environment are you running your code?"

Re: Winscp assembly getting timeout

Did you try to play with Windows Scheduler task settings? Particularly with the "Security Options".
