Hi @pacificsofttechltd,
The error means that FileZilla tried all available authentication methods and have not succeeded. In your case, there was only public key authentication method available
Here, you have two options, one would be to enable password authentication and the other would be to add your ssh key to your FileZilla application.
Add SSH Key to FileZilla
Open your FileZilla, go to Edit->Settings->SFTP and there click on Add key file. From there go to your SSH key and add it.
Enable Password Authentication
SSH to your droplet
ssh root@DropletIp
and edit your /etc/ssh/sshd_config. In there search for the following line PasswordAuthentication. By default it’s commented and set to No
# To disable tunneled clear text passwords, change to no here!
#PasswordAuthentication no
To enable it change it like so
# To disable tunneled clear text passwords, change to no here!
PasswordAuthentication Yes
Save the file and exit. For the configuration to be loaded, you’ll need to restart sshd
service sshd restart
That’s it, you are ready to go
Regards,
KDSys
