Your site as no security!! Nothing is showing up as secure on your site.
Just because you built or have a website, doesn't mean it will open because you "launched" it. Depending on the internet you, or someone else, is using along with the security settings on the device, it won't open if there are security issues present. It protects the user from hacks, vulnerabilities, etc.
Get some security on your site! Check your settings. And you should be fine.
