WinSCP version 5.9.4 on Windows Server 2012 R2 Hyper-V virtual machine

Transfer protocol: SFTP

We do a scripted transfer of 2 files daily, 4 and 5 GB per file. It works 1 or 2 times per week, the other transfers fail.

The script:
Code:
open sftp://{user}:{password}@{servername}/ -hostkey="ssh-rsa 2048 {hostkey}" -rawsettings SendBuf=0
put -resumesupport=on C:\Backups\{file1} /backup/
put -resumesupport=on C:\Backups\{file2} /backup/
exit



The error:

Code:

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

To generate the session log file, use /log=path_to_log_file command-line argument. 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.

Hi Martin,
The company that manages the server has installed a new server with up-to-date software. We don't have the same issues with the new server.
Thanx for your help!
