    Hello, I'm on Jenkins LTS v1.565.2 + ec2 plugin v1.24 I already have my own key pair as we now are trying migrate to using ec2 plugin for autoscaling, so I import my own keypairs on AWS EC2 console, but now supplying the same private key to ec2 plugin don't seem to work. I do see an ec2 instance is created and running, just can't get Jenkins ssh into that slave. {code} Node aws builder (i-83605288)(i-83605288) is still stopping, waiting 5s Node aws builder (i-83605288)(i-83605288) is still stopping, waiting 5s Node aws builder (i-83605288)(i-83605288) is still stopping, waiting 5s Node aws builder (i-83605288)(i-83605288) is ready Connecting to ip-1-2-3-4.us-west-2.compute.internal on port 22, with timeout 10000.

    [JIRA] [ec2-plugin] (JENKINS-30284) EC2 plugin too aggressive in timing in contacting new AWS instance over SSH

    Using Ecualyptus slaves, it can take a while before the DNS name is populated with the correct IP is referenced by the name. Until then, euca-0-0-0-0.eucalyptus.eucadomain... is presented. Needless to say, if the ec2 plugin tries to connect to that name, it fails. The mitigation would seem to be to allow a wait before connect option, or a retry option which re-checks dns on retry. I edited the plugin myself to add a dumb fixed 60s delay and that did fix the issue, however this should be fixed properly. Stack trace follows. Connecting to euca-0-0-0-0.eucalyptus.eucadomain.sc.local on port 22. Connected via SSH. bootstrap() Getting keypair...
