I have some AWS CloudFormation stacks which are in the status DELETED_FAILED. There was an issue building these CFTs which caused them to time out originally, and then I attempted to delete them.
When contacting AWS support on a separate issue they mentioned there is a way to clear these up. How can I get remove stacks which are in a DELETED_FAILED status?
Identify the resources that are attached to the stack and delete them manually from AWS web console. You can find the resources attached to your stack in the cloud formation stack details. And then you should be able to clear the stack in DELETE_FAILED status.
Hope this helps for you.
