To test your situation, I did the following:

• Went to the EC2 management console
• Created a new keypair and saved the key to disk
• Launched a new EC2 t2.micro instance, selecting the keypair I had saved and "Allow SSH traffic from 0.0.0.0/0"
• To test the EC2 instance, I used SSH to connect to the instance, specifying the keypair (I had to chmod 600 key.pem first`) -- the logon was successful
• Downloaded and installed Cyberduck (I'm on a Mac)
• Configured Cyberduck:

• Opened the connection -- it was successful.

Hopefully the above steps will help you figure out what is going wrong on your attempts.

Theoretically, if you can SSH into an instance then you can also use SFTP with it, since they connect in exactly the same way.
