Cannot connect to SFTP-SSH server on port 22

We've been running WinSSHD from BitVise for a couple of years here. No problem with FileZilla at all until the latest release ( Suddenly we're unable to connect to our BitVise WinSSHD server and perform FTP functions.

FileZilla error messages are:
Status: Connecting to
Response: fzSftp started
Command: open "CISNOPLN@…" 22
Command: Pass:
Error: Authentication failed.
Error: Critical error
Error: Could not connect to server

Previous version of FileZilla still successfully connects to the BitVise WinSSHD server, so I'm inclined to believe something got "broken" in this latest release.

Further testing this afternoon reveals:

  • Downgrading to a previously known working version ( does NOT resolve the issue on a workstation that had been upgraded to
  • In the event that "downgrading" is somehow different than a complete uninstall, we also tried completely uninstalling, cold booting the Windows PC, and then installing That produced the same failure.
  • Using version on a workstation that has never been upgraded to continues to work. We continue to be able to connect to our BitVise WinSSHD SFTP server using FileZilla on multiple workstations that have never been upgraded to

If downgrading doesn't revert the problem, it's a clear sign that some firewall, virus scanner or so-called security solution is blocking FileZilla. Get rid of such useless software, with proper configuration you are secure without.
