App Engine Custom Domain Mapping Issue: Domain not mapping to App Engine services after 48 hours

[kathelan]

Hello,

I need assistance with custom domain mapping in App Engine. Let me explain my main issue:

I have implemented two services, backend and frontend apps, in App Engine. The frontend uses the default service name. I decided to buy a new domain name on GCP Domains and started custom mapping my application. I received special IPv4 and IPv6 addresses for A and AAAA record sets with blank DNS names, so I added them all in the Cloud DNS zone. However, after waiting over 48 hours, my IP addresses have not yet been mapped to my domain.

I have searched extensively on forums and read all the documentation about App Engine domains. I didn't try using the dispatch configuration because I believe the App Engine dashboard should map the domain to my default service, as I understood from the documentation. Unfortunately, I cannot find a solution, and I would greatly appreciate any guidance or hints. Thank you.

Hi @kathelan,

Welcome to Google Cloud Community!

Based on this documentation on mapping custom domains, you need to update your DNS records at your domain registrar so that your DNS records will be updated. 

You will only use the dispatch config if you're going to use wildcards and wildcard mappings are not supported for managed SSL certificates.

Hope this helps.
