Deploying the stack: Stack has an error around the WebserverGroup resource creation/set up

[jodiefostersarmy]

Hi Ben/all,

I've been trying to deploy the stack and I seem to get an error when it is creating resources in the WebServerGroup section. It seems to be able to create the EC2 ASG with 2 resources for the WebApp and WebServer, however at some point it rolls back and deletes the resources that the stack and nested stack have created.

I get the error in the screenshot attached:

Failed to receive 2 resource signal(s) for the current batch. Each resource signal timeout is counted as a FAILURE.

Note:

• I am using the latest Amazon Linux 2 AMI in the ap-southeast-2 region for this CFN stack template.
• I have udpated the NetworkStackTemplateURL to my own S3 bucket with updated region references in the network-stack.json file

I'm a little confused as to what exactly it is that might be causing this issue -- having a stab in the dark, I have a feeling it may be to do with the DNS records and my route53 setup?

I've tried reading this page, but I can't seem to see how to pause/prevent the rollback if an error occurs at any point.

Any help is much appreciated, and feedback on how I could improve my troubleshooting skills are appreciated even more.

Thanks! JFA
