AWS MWAA Cloudformation stack creation failed with NotStabilized

Cloudformation returning below error while creating AWS MWAA cluster:

Resource handler returned message: 'Creation failed' (Request Token: 123..., HandlerErrorCode: NotStabilized)

IAM Policies, Roles and Subnet configurations are good We are trying to create MWAA cluster in a VPC where all subnets are private. So there are no NAT Gateway / instances connecting to external world. Webserver access mode is private only.

Please let me know what are the things we have to consider to solve this issue.

Private subnets and private web server mode are fine, but there are a few pitfalls. Have a look at AWS' troubleshooting page.

Make sure you have a S3 gateway endpoint in place. Check the logs (see same link).

In case you provide a requirements.txt be aware of the fact that MWAA needs internet access to install the python packages from pypi.org. To overcome this you can provide wheel packages with your plugins.zip.
