Hi@akhtar,

Actually the key you have created is not in proper format. AWS is unable to read that key. So Create your key in proper format. You can use the below given command.

C:\Users\NADIM AKTHAR>aws ec2 create-key-pair --key-name MykeyPair  --query "KeyMaterial" --output text > MykeyPair.pem

Hope this will help.
