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.

Answer 1

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.
