The most simple way to explain DNS is to say that it turns names (or URL, such as google.com) into IP address. So when you type google.com in your browser calls a DNS server and turns it into http://172.217.9.14/ which is the way you access Google's search page.
When we deliver the Cangooroo front to any client it has an unique URL like frontXYZ.cangooroodns.com.br where frontXYZ is your front unique identification.
As a Cangooroo client you probably want to use your own domain, such as www.yourcompany.com, and that is why you need to configure the DNS for the domain yourcompany.com to point to your front.
Please don't forget to have the chosen domain correctly configured in Cangooroo.
The first thing is to be sure that our support team has been informed of your desired URL so the front can be setup accordingly in Cangooroo system.
In order to configure your domain to work correctly we have put toghether some instructions:
Cloudflare (we recommend this service for DNS)
We do not support specifics on the configuration but if you have any doubt please feel free to contact our support team and we'll try our best to help you.

You don't need to worry about TSL/SSL certificates. Once your configuration is correctly done the certificate will be issued and attached to your front. You don't pay anything to have the certificate, it is part of the front module.
If you do a redirect of the root domain to the URL www.yourdomain.com the URL configuration on Cangooroo's Intranet should be www.yourdomain.com.
