Hello.

Does the IAM user you are using have a policy attached that allows access to S3?  
Also, if you look at the CloudFormation template, it is a nested stack and references external S3.  
It is possible that access to this S3 is not working properly.  
Please do not change "QSS3BucketRegion" in the parameter.  
```
https://${S3Bucket}.s3.${S3Region}.${AWS::URLSuffix}/${QSS3KeyPrefix}submodules/cfn-ps-aws-vpc/templates/aws-vpc.template.yaml
```
