wso2 API Manager AutoScaling Group Not Creating - wso2-api-manager

Question

I've been trying to use the stock templates from the wso2 website to deploy wso2 to AWS. The CloudFormation stack fails to create because the auto scaler fails to create.
I checked the EC2 instances and the actual instance is running and healthy.
I SSH'ed to the instance and ran:
grep -ni 'error\|failure' $(sudo find /var/log -name cfn-init\* -or -name cloud-init\*)
to check the log files for errors or failures. I didn't find any.
I then tried to run:
/usr/bin/cfn-signal -e $? --stack ${AWS::StackName} --resource WSO2MINode1AutoScalingGroup --region ${AWS::Region}
from the correct instance. I filled in the correct information manually when I ran the command on the instance. I pulled this command from the YAML file from the wso2 website. This command returned an Access Denied error for the stack.
Any help would be greatly appreciated. I feel like I'm over looking something simple. I included the LaunchConfiguration and the template for the Auto Scaling group below if that's useful. Happy to provide other information.
