Let's Encrypt Cert not created for www

Hi I have setup a custom domain that is registered with GoDaddy and the have setup an A record and CNAME for www. The DNS has propagated globally now and I have verified the records are correctly setup. In my Netlify project the DNS has been verified, but only the root domain: americanroadrally.com has the Let’s Encrypt cert attached properly. The www doesn’t have the cert correctly installed. I have tried to renew the cert and I get this error message:

americanroadrally.com doesn’t appear to be served by Netlify

We can’t renew your Let’s Encrypt certificate automatically until the issue is resolved. Check our troubleshooting guide for more information on how to fix the problem, and then renew the certificate.

Any help would be appreciated. Thanks!
