SFTP file transfer fails

#1 Post by brucem11 » 2020-09-28 15:54

Trying to download files from an SFTP server. I can successfully connect, browse folders, change directory, rename folders, and create a new file on the remote server. I can upload a file to the remote server. But downloads are failing: Here's an example session:

Status: Connecting to sftp.xyz.com...
Status: Using username "XYZ".
Status: Connected to sftp.xyz.com
Status: Starting download of /File.piz
Command: cd "/"
Response: New directory is: "/"
Command: reget "File.piz" "D:\Data\File.piz"
Command: reget: restarting at file position 0
Command: remote:/File.piz => local:D:\Data\File.piz.piz
Command: reget: restarting at file position 65536
Command: remote:/File.piz => local:D:\Data\File.piz
Error: FATAL ERROR: Network error: Software caused connection abort

Using Internet Explorer, manual download succeeds. Using WinSCP automatic download succeeds.

I've been told that the SFTP server is an "EFT server" which only supports these commands:

Any help?

Using Internet Explorer, manual download succeeds.
Would be total news to me that IE supported SFTP. It doesn't, IE only supports FTP (the most plain, basic one without any encryption). So, you are connecting with IE using FTP, a different service. Question: Does it work if you use FTP with IE (not SFTP)?
Using WinSCP automatic download succeeds.
What protocol is used? WinSCP supports FTP(S), SFTP and SCP in this context.
