Elastic Beanstalk Environment Creation: DNS name not available

I'm trying to create my elastic beanstalk environment via the eb cli. When I run 'eb create restapi-prod', I get an error saying:

DNS name (restapi-prod.eba-mnpbn63s.us-west-2.elasticbeanstalk.com) is unavailable.

Why is this happening? Even when I tried adding a random string to the end of the environment name 'eb create restapi-prod-dtyq5r4' I still got the same erroring issues.

Note: I plan on placing my elastic beanstalk app behind an api gateway, so I don't need a route 53 record at all.

Here is my full configuration file:
