Hello,

You would need to add your SSH key to your SFTP client. For example if you are using FileZilla you need to launch Filezilla and choose Site Manager from the File menu, and fill up the information there:

Hostname - Your droplet's IP address

Port: 22

Protocol: SFTP

Logon Type: Key file

User:  root

Key file:  Click browse and load your Private SSH key

Then you should be able to authenticate as normal.

Hope that this helps!
Regards,
Bobby

In FileZilla Erro: Disconnected: No supported authentication methods available (server sent: publickey)

In Console (ssh root@ip) = “Permission denied (publickey)
