Resolved Plesk FTP/SFTP Fix CentOS, Ubuntu, Debian

[mdraselkhan]

Hello,

Are you facing an error during an FTP/SFTP connection? As a default, sometimes you are not able to connect your server over the FTP/SFTP without ssh key file. So If you follow this guide you will able to connect your server over the FTP/SFTP.

1. Edit the /etc/ssh/sshd_config file [$ vi /etc/ssh/sshd_config]
2. Change PasswordAuthentication and ChallengeResponseAuthentication "no" to yes
3. Then scroll down until you see this line "Subsystem sftp /usr/lib/openssh/sftp-server"
4. Disable the line by adding a has sign starting the line, [#Subsystem sftp /usr/lib/openssh/sftp-server]
5. Under the above line write/add this like [Subsystem sftp internal-sftp]
6. Then restart ssh [$ service sshd restart]
7. Filezilla: On the hostname field, use server hostname then enter your FTP username & password with Port 22. Make sure Port 21 & 22 open on your server.
8. No ssh keys are required for these connections.

Thanks to @cepimojico
