Create VPC - Workflow build failing - AllocateAddress

Question

Hi,

After many attempts to use the new create vpc tool that builds the VPC, subnets, gateways, etc. I keep getting to the point where it is allocating IP's and it fails.  I have full admin permissions, have checked that I can allocate elastic IP's and we have plenty of quota left.  I checked the cloud trail logs and see:

"eventTime": "2022-03-02T21:13:57Z",
    "eventSource": "ec2.amazonaws.com",
    "eventName": "AllocateAddress",
    "awsRegion": "us-east-1",
    "sourceIPAddress": "AWS Internal",
    "userAgent": "AWS Internal",
    "errorCode": "Server.InternalError",
    "errorMessage": "An internal error has occurred",
    "requestParameters": {
        "tagSpecificationSet": {
            "items": [
                {
                    "resourceType": "elastic-ip",
                    "tags": [

Thank you!

Answer

Given that it says "An internal error has occurred" I'd suggest that creating a support case is the right step here. There's a lot more information required to troubleshoot this - things like IAM permissions, VPC setup, subnet allocations, etc. and the support team have better visibility of your VPC configuration to help.
