I'm configuring the DNS of my domain in the Registry using the PointDNS (as an add-on to Heroku).
Setup was done following this article: link
Everything worked and my application is running. The problem is that when I try to add Automated Certificate Management (ACM). I can not add the myapp.com.br.herokudns.com and www.myapp.com.br.herokudns.com domains (provided on the dashboard) in the RegistroBR, therefore, they fail when Heroku tries to verify.
At the moment I use the addresses provided by PointDNS (similar to what is shown in the Medium article).
Which addresses should I use? Do I have to do any other configuration in the registryBR?
