SSH & SCP works, but not SFTP

Hi there, I use Putty for SSH and WinSCP for file transfers without issues authenticating with a PPK key file on my computer. WinSCP is set to "Use SCP fallback" if SFTP fails. While adding a service today that is to log inn to the server via SFTP to change some file names on demand, I am unable to log in. While troubleshooting, I try to connect with WinSCP without the fallback and it fails, stating "Are you sure this server is running an SFTP server?" or something of the likes. The line "Subsystem sftp /usr/libexec/openssh/sftp-server" is in my sshd_config file. I have restarted OpenSSH several times. Anyone have a clue as to where I could look for a solution?

  Hello :) Have you tried using an alternative SFTP client such as FileZilla, or just using it from the command line, to determine if the issue is isolated to WinSCP? Thank you.

  Hello, I have now and it does not work and I get an exitcode 127. Does the "SubSystem" line also have to be in ssh_config or just sshd_config? Anything in ssh_config I should be looking for?

  That line should exist in /etc/ssh/sshd_config, but you should not have to add it in because it's used by default. Do you have any firewall rules enabled that could be restricting access? Thank you.

  Sorry for the late reply. Not that I am aware of, is there an easy way to check iptables specifically for something on port 22 that would block SFTP? I would think it's fine since SCP works, but what do I know.

  You could install a firewall management utility such as CSF to more easily manage your firewall rules. Otherwise, feel free to open a support ticket using the link in my signature so we can take a closer look. You can post the ticket number here so we can update this thread with the outcome. Thank you.
