No supported authentication methods available (server sent: publickey) while using FTP

I have created an EC2 instance and it's working. I have created the FTP users and passwords successfully. Now while connecting FTP using FileZilla. I am getting below error

Command:    open "ftphyb@ec2-3-8-24-114.ca-central-1.compute.amazonaws.com" 22Status:         Using username "ftphyb". Status:         Server refused our key Status:         Server refused our key Status:         Server refused our key Status:         Server refused our key Error:          FATAL ERROR: No supported authentication methods available (server sent: publickey)Error:          Could not connect to server

Any Idea what is the issue?

The above IP details and FTP are wrong and it's only for demo purposes.
