@kmr: What version of WinSCP?

Below issue happens only in Production server not on Staging or Dev.

Dev, Staging and Prod both are on Window 2012 R2 with .NET Framework 4.5 & 4.0

Ftp Get Error: Timeout waiting for WinSCP to respond - WinSCP has not responded in time (response log file C:\Windows\TEMP\wscp09D4.00EE499F.tmp was not created). This could indicate lack of write permissions to the log folder or problems starting WinSCP itself. at WinSCP.Session.CheckForTimeout(String additional) at WinSCP.Session.Open(SessionOptions sessionOptions) at Lecorpio.BLL.ETIF.Ftp.Providers.WinSCPBaseFtpProvider.Get(FTPPortInfo ftpPortInfo, String localFileName) at Lecorpio.BLL.ETIF.Ftp.FtpClient.Get(Guid integrationPortId, String localFileName)Transport Type: SFTP

Hello, you will find solution to this bug,thank you very much.

Thanks for your report.

Can you send me an email, so I can send you back a debug version of WinSCP to track the problem? Please include link back to this topic in your email. Also note in this topic that you have sent the email. Thanks.

I get the following error from .NET when trying to run WinSCP from a web app:

Failed: Timeout waiting for WinSCP to respond - WinSCP has not responded in time (response log file C:\Windows\TEMP\wscp10DC.0191F3F3.tmp was not created). This could indicate lack of write permissions to the log folder or problems starting WinSCP itself.

I can run it from the GUI, but when I run from the web app, it produces that error. Also on my development computer, when debugging in VS, it actually works when called from the web app, only when I publish to the production server it produces that error.

The DLL version info is:
File version: 1.2.6.5125
Product Version 5.7

The production server is running Windows Server 2012 R2 Standard.

I turned on logging, and noticed that there is no log entry when trying to call it from the web app.
