Hello @ReWild

This can happen when the CNAME isn’t yet configured before adding it to app. Our TLS certificate issuer caches the NXDOMAIN (not found) DNS record, and the TLS certificate issuing is delayed. Normally it resolves automatically once the NXDOMAIN cache expires in about 30-90 minutes.

We are working on improving that for cases like this when the domain CNAME is only recently created.

If you are still experiencing an issue after 90 minutes then please reach out to the support team.
