It is just a permission issue with your aws pem key.
Just change the permission of pem key to 400 using below command.
chmod 400 pemkeyname.pem
If you don't have permission to change the permission of a file you can use sudo like below command.
sudo chmod 400 pemkeyname.pem
I hope this should work fine.
