Why is my instance terminating immediately after launching or starting an instance?

Last updated: 2020-03-30

My Amazon Elastic Compute Cloud (Amazon EC2) instance state changes from pending to terminated immediately after launching a new instance, or after starting a stopped instance. How can I troubleshoot this issue? 

Resolution

First, determine the termination reason using the Amazon EC2 console or AWS Command Line Interface (AWS CLI). Then, follow the troubleshooting steps for that reason. For more information, see Instance Terminates Immediately.
