Hi all,

"Server unexpectedly closed network connection" shown and program exited
when we used Putty's psftp(0.6) to put files to remote SSH2
server(GlobalSCAPE Enhanced File Transfer Server (v. 5.1)), the issue always
occurs during file transfer.

Any fix?

Thanks,
Alan

next step is look at the remote server log. Talk to server personnel and
tell them your client IP. I won't bring up more advice before this has
been done.

Ok, thank you.
