Hi, I'm trying to validate a public certificate requested from ACM with CNAMEs dev-application.customer.com and *.dev-application.customer.com.
In this case DNS-name customer.com is registered outside of Route53. I created Public hosted zone on Route53.
For certificate validation I was able to add records to Hosted zone with AWS Console, after few hours validation is still pending.
I'm able to make http-requests to dev-application.customer.com after adding IP for one of mentioned NS-records into my /etc/resolv.conf.
Without this dev-application.customer.com can't be resolved.
Might that actually be the reason why certificate validation is pending - ACM's doesn't resolve the hosted zone as it isn't available at customer.com DNS?
