I'm getting the error mentioned in subject line. The below article suggests turning off the 'optimize connection buffer size' if problem persist. So I did, followed the article and turned off that option. But still it doesn't help. I'm running the WinSCP.com interface.
Also, after the server replied the transfer completed at 99% which is really odd. It tried to turning on logging for the command interface (WinSCP.com) but that doesn't work.
Could you please advise what I can try, to solve both the timeout as well as the download completing at 99% as opposed to 100%?
