I was connecting to Amazon EC2 through SSH and it was working well.
But
all of a sudden, it stopped working.
I am not able to connect anymore with the same key file.
What can go wrong ?
Here's the debug info.

I've already googled everything and checked :
Public DNS is same (It hasnt changed),
Username is ubuntu as it's a Ubuntu AMI ( Used the same earlier),
Permission is 400 on mykey.pem file
ssh port is enabled via security groups ( Used the same ealier )
