What are the eligibility criteria for registering this domain name?
.app domain names are an encrypted-by-default TLD by virtue of being inscribed in the HSTS Preload list. As such, websites hosted on .app will not load on modern browsers unless they are served over HTTPS (ie. with an SSL certificate).
Before a .app domain name will resolve in browsers an SSL certificate will need to be installed. You can purchase applicable SSL certificates through Bazinga Hosting & Domains or alternatively if you purchase a web-hosting page through Bazinga Hosting & Domains you will be provided with an SSL certificate through Auto SSL automatically.
In the event that you purchase an SSL certificate through an external provider and require this to be installed onto a Bazinga Hosting & Domains hosting service please contact our technical support team for assistance with installation.
