Could not retrieve directory listing

Hi,
I use this version WinSCP 5.2.1 (running in Win XP, Win 7 and firewalls are disable) and Filezilla Server 0.9.41.
I have a problem with the synchronization of files, the messages appear randomly on GUI and scripting with Powershell (2 and 3):

"Timeout detected.
Could not retrieve directory listing
Connection accepted
Error listing directory"

Session parameters :
FTP with SSL/TLS Implicit encryption
Port 990
Passive mode
Synchronize parameters
Direction : Local
Mode : Synchronize files
Synchronize options : Delete files, Preview Changes
Comparison criteria : Modification time, File size
Transfer settings : Binary

Transfer runs with another FTP client and Filezilla Server as WinSCP and another FTP Server (CrushFTP)

The parameters of session can't be modified

Thanks for your answer

Please attach a full log file showing the problem (using the latest version of WinSCP).

This problem occurs randomly and cut the connection to the FTP server.

Thanks for this reply

Thanks. Can you please also provide a session log for a successful scenario?

Thanks for your quick reply.

I'll attached files for a successful scenario.

Thanks. I did not find any clue yet. Do you have an access to server-side logs?

Hi,
The Filezilla server logs are identical to the file LogSession.
Sorry, I don't have more information to provide you.
