Please compare session logs from GUI and scripting to find what makes the difference. If you cannot resolve this on our own, please attach both (complete) logs.

Batch file command:
winscp.com /command "option batch abort" "option confirm off" ""open sftp://login:password@address -hostkey=""*******************" "" "put ""location\Test.csv""" "exit"

Get error message: Network unreachable - when run batch file

Can login to WinSCP client and connect SFTP without a hostkey and transfer manually, but want to automate.
Verified Hostkey to use in batch file.
Please advise. Thanks
