Terraform: ssh: handshake failed: ssh: unable to authenticate, attempted methods [none publickey], no supported methods remain

[perryluopl]

Terraform Version

Terraform v0.11.7

• provider.aws v1.27.0

### Terraform Configuration Files

connection {
user        = "centos"
private_key = "${file("${var.key_path}/${var.key_name}.pem")}"

}

Code below is not working either.

connection {
user        = "centos"
host = "${aws_instance.cdh_server.public_ip}"
agent = false
private_key = "${file("${var.key_path}/${var.key_name}.pem")}"

}

```
