EC2 权限被拒绝（公钥）

Question

I am trying to connect parse server EC2 instance. But in ubuntu terminal after pasting ssh -i "instame.pem" admin@ec2.ap-south-1.compute.amazonaws.com, error is coming as permission denied(public key). I have checked every thing and it is fine. As the instance plat form is Debian then the user name is admin. Despite of writing the expected command why I am getting the error?

Answer 1

"Permission denied (publickey)" and "Authentication failed, permission denied" errors occur if:

• You're trying to connect using the wrong user name for your AMI.
• The file permissions within the operating system are incorrect on the instance.
• The incorrect SSH public key (.pub) file is in the authorized_keys file.

Double check these before attempting another connection.
