Apparent website security issue?

I've just set my new site to live, but when I tried to follow the link to test it, I received a big warning saying the site isn't secure and trying to direct me away. There's no opportunity for anyone to enter sensitive information anywhere on it, so I don't understand what the issue is. Has anyone had this problem or does anyone know how to solve it? This is the link: www.ellenthalediting.com

It can take up to 72 hours for an SSL certificate to propagate throughout the internet. It may speed up the process if you were to ensure secure preference is checked under Home > Settings > domains >developer tools>SSL and make sure HSTS is checked.
