The .dev extension is a secure namespace, meaning you will need an SSL Certificate installed on your website before it can be viewed in a browser. .dev domain names come pre-submitted to the HSTS Preload list, which in effect makes them HTTPS-only. If you require an SSL certificate, you can purchase one through the VentraIP website or through your VIPcontrol account. Alternatively, if you have a hosting service with VentraIP, you will be provided with a free Auto SSL Certificate. Auto SSL Certificates are installed automatically on your web hosting service. In the event that you purchase an SSL Certificate through a third-party provider and need assistance installing it on your VentraIP hosting service, please contact our technical support team. What will happen if I don’t have an SSL Certificate installed? Frankly speaking, your website won’t be accessible and a browser error will occur when you visit your “dev” domain name.
