you can close this out. turns out the issue was with the permissions on the SFTP server. thank you for the help.

here is log of winSCP from code.

here is log of winSCP log from interface

Please attach the full log files.

I am using the most recent version 5.9 of winscp. Using the client interface I can get a file to upload. It has errors but if I change transfer settings, uncheck transfer option of preserve timestamp, the upload goes through just fine. If the file is under 20k, it goes through just fine. The SFTP server on the other side is globalscape.

as part of a batch process, I am using C# code for WinSCP to upload the file, but it will not no matter what I change. I have made the preserve timestamp setting through code as false to match the interface. I have looked at the log files and noticed some differences in settings but don't know what they are to change and try to match. One of those differences I notice in


WinSCP interface log:

C# code log:

the one setting I cant figure out is
PrR: No (No);
Or
PrR: Yes (No);

Anyone know what those are? I get this error when trying to upload with c# code.
