SFTP : No supported authentication methods available

While accessing FTP with SFTP,we get the following error:

No supported authentication methods available.

If try to work with normal FTP and it might work fine but SFTP will not.

For this just check the file /var/log/secure on the server,We find error message as:

Received disconnect from XX.XX.XX.XX: 14: No supported authentication methods available

The problem is faced due to PasswordAuthentication setting in /etc/ssh/sshd_config.

If the setting Password Authentication is disabled in the SSH configuration file SFTP will not function. For this you can set PasswordAuthentication to on.

PasswordAuthentication on

Once you edit the file save and restart the sshd service using the command:

/etc/init.d/sshd restart

Now try to login the SFTP again.
