Network Unreachable error Message using scripting

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

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.
