Please attach a full session log file showing the problem (using the latest version of WinSCP and if possible even using 5.7.7).

Log Transfer02
Files after FTP

for example:

File: '1484606814552.jpg' [2017-01-16T22:46:54.710Z]
after transfer '1484606814552.jpg' 17.01.2017 11:25

settings for transfer01

Can you please attach a log file using WinSCP 5.7.7 for comparison?

The server behaves differently in the session for 5.9.3.

While it would be strange, one of the reasons might be that with 5.7.7, you use TLS/SSL, while with 5.9.3 you are not.

I'm using TLS/SSL only with one connection with the old WinSCP. The other two are without encryption on both (old/new) WinSCP. The appearance is the same with three different connections / servers.

I'll try to recreate the settings, I've imported them from the old WinSCP.

Hmm ... I tried and updated the old WinSCP to the current version. There it is working.

Have you heard anything that a Sophos firewall could intercept the ftp communication and alter the Date / Time?

Your feedback from email:

I've talking to a IT-Sec guy responsible for the firewall.

He told me that the firewall is intercepting the ftp traffic with ftp proxy for content check. He thinks that the command for keeping date / time -

MDTM he mentioned - may not be implemented in the sophos ftp-proxy.
