I have sent you a new package. Let's continue via email.

Successful transfer, but timeout error using FTP

It appears that the zip file only contains winSCP.exe. The problem doesn't happen if I run the client, only when I use the dll from code. Do you have a debug version of the dll?

Thanks. Though it unfortunately did not give any more information.

I have sent you an email with a debug version of WinSCP to the address you have used to register on this forum.

Can you enable a more verbose logging using Session.DebugLogLevel = 1 (or 2)?

I'm not sure why, but the timeout error didn't happen once I started writing to the log. But the delay still happens - if you look at the log snippet below (IPs removed) the download gets started, then there is a 30 second delay and its restarted. When there are multiple files, its an extra 30+ seconds for each one. These are tiny files and should take no time to transfer. Maybe you can tell why it fails the first time and then has to restart?

I do not see any timeout in the logs. Please make sure you have attached logs for the session that has timeouted.

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.

A debug log file (Session.DebugLogPath) might be useful too.

Successful transfer, but timeout error using FTP

I have been using the WINSCP dll successfully for several integrations that have sFTP sites (the code is written in X++; a .NET 'variation' used in Microsoft Dynamics AX) We have version 5.15.5 (Build 9925). We have one vendor that still has us using an FTP site, but plans to upgrade to sFTP 'soon'. The current code is working fine (not sure exactly what its using) but I thought I would upgrade it to use Winscp and then could just switch the protocol on the session options when the vendor was ready to upgrade us.
The connect works, i can do an EnumerateRemoteFiles to make sure the file I want exists, but when I do a GetFiles it hangs for a minute, gives me a Timeout waiting for WinSCP to respond error but successfully transfers my file! The Putfiles works fine with no timeout or error. Any idea what might be happening? Any help would be greatly appreciated.
Thank you.
