I am new to Amazon EC2 and trying to configure it. I have created the instances and trying to connect. I am getting the error as "Disconnected : No supported authentication methods available (server sent :publickey)".

I have got the keypair from EC2 Management console and have used putty gen to generate private key file(PPK).

Kindly assist to resolve.

Make sure you are using the right user name. There are different usernames for different EC2 instances.

  • Amazon Linux: ec2-user
  • Ubuntu: ubuntu
  • Debian: admin

For most of the other instances, you can use ec2-user.
