Cause

  1. Password is incorrect.
  2. Password authentication on the target server is disabled (only Challenge response is enabled) - Cloudlink is using password authentication for sftp backup store, but not challenge response.

Resolution

If it is not the incorrect password case, check the file /etc/ssh/sshd_config on the target server, find “PasswordAuthentication” setting.
If PasswordAuthentication is set to “no”, change to “yes”, then restart the ssh service.
For example: “systemctl restart sshd.service”.
