1. 1. 1. Summary

When I try to create a new VPN with `amazon.aws.ec2_vpc_net` (collection v8.2.1) the *VPC is created in AWS* but the Ansible task fails (after some time) with this message:
> Failed to wait for IPv6 CIDR association

I can get no other details from Ansible

1. 1. 1. OS / Environment

MacBook Pro
Chip: Apple M1 Pro
macOS: Sonoma 14.6.1
GNU bash, version 3.2.57(1)-release (arm64-apple-darwin23)
Homebrew 4.4.2

1. 1. 1. Steps to Reproduce

Tested with this simple playbook.
<!--- Paste example playbooks or commands between quotes below -->
```yaml (paste below)

• name: Deploy AWS infrastructure
  hosts: localhost
  gather_facts: false
  become: false
  tasks:
• name: VPC
  amazon.aws.ec2_vpc_net:
  name: "jira-dev2-vpc"
  cidr_block:
• "10.234.4.0/22"
  dns_hostnames: false
  dns_support: true
  ipv6_cidr: false
  tenancy: "default"
  tags:
  env: "dev2"
  app: "jira"
  state: present
  register: vpc
  ```

1. 1. 1. Expected Results

Since VPC is correctly created in AWS, I expected the task to succeed in Ansible as well.

1. 1. 1. Actual Results

VPC is immediately created in AWS, but the Ansible playbook seems stuck for 5 minutes, then fails like this:
```console (paste below)
TASK [VPC] **************************************************************************************************
fatal: [localhost]: FAILED! =>

{"changed": false, "msg": "Failed to wait for IPv6 CIDR association"}

```
