FreeBSD 11.1 AMI Asks for Password

[Sridhar Ayengar]

Hi.

I am trying to launch a FreeBSD 11.1 instance.  I create a keypair and 
download it.  Then I launch the instance.  I try to login with the key 
and this happens:

The authenticity of host 
'ec2-34-215-220-77.us-west-2.compute.amazonaws.com (34.215.220.77)' 
can't be established.
ECDSA key fingerprint is SHA256:PqxW+ZTH2XYw8dazEN6xB9H9EJbYkVJxWu0U+xXBK9A.
Are you sure you want to continue connecting (yes/no)? yes
Warning: Permanently added 
'ec2-34-215-220-77.us-west-2.compute.amazonaws.com,34.215.220.77' 
(ECDSA) to the list of known hosts.
Password for root at ip-172-31-42-111:

Any ideas of what might be wrong?

Thanks.

Peace...  Sridhar
