I am facing the issue in connecting server via putty. The error is showing me is "Server Refused our key: AWS - Disconnected: No supported authentication methods available (server sent:publickey)".
I am logging in with username " ubuntu ".I checked lots of websites but I didn't find any solution. I create a new key-pair file( .pem ) and tried again that's also is not working. I am using the same key name for the pem file. Then using pem file I am creating a ppk file and then it is not working
