I have an Aws EC2 instance that have been running for some months without any problems.
Today, when i wanted to access it using ssh:
ssh -i "DRUID_PROD_NEW.pem" ec2-user@eX.X.X.x.compute-1.amazonaws.com
i receive a
Permission denied (publickey).
It worked well yesterday but now I can't connect. I have not made any changes on the server for the past months.
I had exactly the same problem back in february. I had to make a new instace, and copy everything over. It was one hell of a job and i will quit Amazon completely if this is the norm.
I appreciate any help.

Thanks Kim
I found out what was wrong.
Some weeks ago I changed the ec2-user directory to group readable. It obviously leaves the machine inaccessible. I completely forgot about that and today when i needed to access the machine i received the infamous error.
So, changing the permission back to 755 for the ec2-user home directory solved the problem.
Thanks for taking your time to try to help me out of this situation.
