Re: Connection has been unexpectedly closed Server sent command exit status 0

Does WinSCP GUI work? If not, can you connect and work with the server using any other SFTP client running on the same machine as WinSCP?

Not sure if you have any updates as to why this is occurring if its something I'm doing wrong or on the server side? But to give you an update, I've attached an updated log file. I attempted to try and run my script today 5/6/2020 at 14:59 in the log file and from there you can see I authenticate correctly and it seems like it finds the remote directory, but I can't confirm that a transfer has been successful. IT also ends with the same error session sent command exit status 0. Attached you can find the updated log and my script is found here below, I just got it from going to the file and choosing upload -> transfer settings -> generate code and I changed it to command line. 

/log="C:\writable\path\to\log\WinSCP.log" /ini=nul /command "open sftp://Gallagher@qa.gis.parker.com/ -hostkey=""ssh-rsa 1024 1IXtQwUc5xhTwaynYWTjNelGlvvQaURyUMX+eWbanVY="" -privatekey=""C:\Users\iZap\mykey.ppk"" -rawsettings ProxyPort=0" "lcd C:\Users\iZap\Documents\Parker" "cd /" "put -rawtransfersettings[1] IgnorePermErrors=1 *" "exit"

Hey I'm trying to write a script to automatically upload a file to another company's FTP site, but I am running in circles and keep getting the same error message. This is my first job and first time trying to write something like this so be gentle. We are not using a password to login, we use a username and a private key to authenticate. Below you can find my script and the log file of the issue.

Script: aka test.txt 
option batch abort

option confirm off

open sftp://Gallagher@qa.gis.parker.com -privatekey=mykey.ppk -hostkey="sh-rsa 1024 2e:b9:10:43:83:55:69:84:0b:f5:b6:40:60:7c:5d:4c"

cd /home/iZap

put C:\Users\iZap\Documents\Parker /

exit
