Try changing the permissions of the pem file. If you are using linux, then the following might work:

chmod 400 keyname.pem

There is a step by step guide on how to connect to an AWS linux instance. You need to have a ppk file generated from the pem file (use PuttyGEN) and use it to ssh using PUTTY to linux instance. (this is if you are connecting from your windows ). Please use steps below:

For connecting from your local linux computer to Linux EC2 : https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/AccessingInstancesLinux.html

For connecting from your local windows computer to Linux EC2: https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/putty.html

If you've tried all the standard solutions described in the documentation, try deleting the known_hosts file in your ~/.ssh directory as contents may have been corrupted.

rm ~/.ssh/known_hosts
