DNS records for an app on a subdomain and a marketing site on root

Website, Application, Performance DNS & Network

I’m running into some issues trying to set up DNS records.

I have an app hosted in Google Cloud’s App Engine. Google provided me with A, AAAA, and CNAME records. I want the app to live on the app subdomain. A and AAAA records are set with @ as the name and the CNAME record is set with app

I have a marketing website and I have an A and a CNAME record. The A record is set with @ as the name and the CNAME record with www as the name.

I’ve gotten it to halfway work for the marketing site with these records:

  • the address with the www prefix works
  • the root domain gives me a google error page

The app is reachable and Google was able to verify the records and issue an SSL certificate.

Anyone know the best way to get the marketing site and the app working 100%?

Welcome to the Cloudflare Community. :logodrop:

@ represents the root or apex name. You cannot use it for both your app and your marketing sites. You will need to pick one.

What names can be used for the A and AAAA records for the app? This is the part that is confusing me. I can’t use ‘app’ because the CNAME record is already using it.

What happens when delete the CNAME and use app with the provided A and AAAA records?
