Jenkins EC2 plugin starts and stops instance immediately when building the job

Question

I am trying to create a new EC2 instance every time when there are no executors or number of jobs are in queues. All the jobs must run on slave node.

For the purpose, I came to know about Amazon EC2 plugin. I have done all the setup required and when I build the job it creates new instance but it also gets shutdown and terminated immediately.

It is also not showing up in Jenkins >> Node

I don't know what is the exact cause. If it's the Idle termination time its set to 30.

Someone let me know the exact cause for it.

What does the jenkins log say about it? You should see entries like "Attempting to provision slave needed by excess workload of 1 unit" - what log entries are after that? — Bruce Becker

For me, this symptom was resolved by allowing full network access between the master instance and the slave instance.
