@yannickF I’m working on using SSH vs FTP for file transfers and deletions as it’s more “natual” in today’s security conscious world.
If you’re able to allow SSH to the remote ends, this may help out with things.
I’ll have to change the text on these fields to remove “FTP” as the main parameter.
As, and this is very much just a guess, the Error is showing specifically teh SFTP subsystem is failing, I am guessing the remote side is not setup (properly) for SFTP, and is instead using the default sshd_config file.
I say this because there’s checks letting you know if you can connect, and if the sftp fails. Since connect has to happen first, that message tells me the configuration on the remote machine needs a minor update.
If you have admin access to that remote node (as well any node you need this to connect to)
Please open the relative machine’s /etc/ssh/sshd_config
Look for the line:
Subsystem sftp /usr/libexec/openssh/sftp-server
Replace it with:
Subsystem sftp internal-sftp
Restart sshd service:
sudo systemctl restart sshd.service
This should fix that particular error message.
