Recently I setup and Amazon EC2 Linux AMI instance to host the ECR and want to connect it to the awesome Cloud 9 IDE. But somehow it cannot connect. I opened the SSH port on the EC2 instance, copied the the public SSH key value (from the cloud9 wizard) into the ~/.ssh/authorized_keys file on the existing instance, but getting the message:AWS Cloud9 couldn't connect to SSH server ec2-user@.....
What am I missing?
