CloudFormation script generates "No subnets found for the default VPC"

Question

I have seem the following error during stack creation in number of AWS provided CloudFormation script. Any idea why its generating VPC error?

Error message:

CREATE_FAILED AWS::EC2::Instance WindowsServer No subnets found for the default VPC 'vpc-aaaaaaa'. Please specify a subnet.

Here is the template: https://s3.amazonaws.com/cloudformation-templates-us-east-1/Windows_Roles_And_Features.template

Answer 1

I was facing the same problem and the below steps helped me.

1. Deleted the subnet of the VPC the error was referring to.
2. Use this command on my shell to create a default subnet:

   aws ec2 create-default-subnet --availability-zone us-east-2a
