Filezilla : error in connecting to amazon ec2 instance

Question

I have created a simple Amazon ec2 instance with all the default values. I have downloaded the key which the instance gave me. Now I downloaded filezilla and created a new site with my public DNS, port number blank, protocol sftp, some username and password, and clicked ok. Then in the edit-> settings I added my private key downloaded from amazon and clicked connect. Still I get following exception:

Error: Disconnected: No supported authentication methods available (server sent: publickey) Error: Could not connect to server

Am i going wrong somewhere?

The reason for the issue can be one among the following

1. You might have used the .pem file instead of .ppk file. Create a ppk file with the pem file and try accessing the instance. You can use puttygen for converting pem file into ppk.
2. Ensure that port 22 is accessible from your network. Verify the security rules present in the security group associated with the ec2 instance.
3. The instance can be inside a private VPC and you are trying to access it outside private VPC.
