AWS ssh error: Permission denied (publickey,gssapi-keyex,gssapi-with-mic)

 I was ssh-ing to AWS EC2 instance and got the error Permission denied (publickey,gssapi-keyex,gssapi-with-mic)

-----------------

sh-3.2# chmod 400 ec2-keypair.pem

sh-3.2# ssh ec2-suer@54.89.86.26 -i ec2-keypair.pem

-----------------

Solution: The solution is just adding the right path, for the key pair that you downloaded. I was in the right folder and I gave the path by just adding "./"

ssh ec2-user@54.89.86.26 -i ./ec2-keypair.pem
