amazon web services - Disconnected : No supported authentication methods available (server sent :publickey)

Question

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.

I have already referred Google server putty connect 'Disconnected: No supported authentication methods available (server sent: publickey) but couldn't get my problem resolved.

For the record, the usual default username in EC2 for these Linux distro:

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

To access the instance through a browser, make sure you add a rule in your security group to allow port 80 and port 443 inbound.
