EC2 Plugin v 1.29
Jenkins 1.624
In every 10 or so instance launches, I see cases where the EC2 plugin opens a SSH connection to the new instance before the time where I believe the corresponding private key has been put in place by the AWS infrastructure during the launch of the instance. As a result, we see errors in the node launch. The output for the launch is below.
