Unable to add SFTP destination to backup Cyberpanel

Have been struggling to get sftp connected to backup our Cyberpanel server, but keep getting errors:

Hello there,

I will recommend you to double-check the disk usage on the Cyberpanel as the server might be close to full and cause this behaviour.

Another thing is if you have Firewall rules in place but this should return a different error from 500 Wrong command.

Also, make sure to double-check the FTP details.
