Question

Why my site which uses "Let's Encrypt" is marked as "not safe" by Chrome?

Hi, I have successfully installed Let’s Encrypt and Firefox marks my website as safe (green padlock). But Chrome marks my site as not safe. Why is that? Did I do something wrong? I followed this guide [1] to the end.

Is it possible to fix this? Should I need to get a non-free certificate?

@Mohsen47 raises a good point. Check the browser console to make sure you don’t have any http links like this http://www.example.com/image.jpg . I generally put //example.com/image.jpg instead. This will default to https if the host server supports ssl while at the same time as your browser checks for http links, it won’t find any and mark this as a secure page.

Regarding the http-https redirect, double check the Adjust the Nginx Configuration to Use SSL section of the guide to make sure you configured the files as directed. Also restart Ngix for good measure. Hope that helps

Are you serving your site with an IP address instead of the secure URL? I was doing this and when I changed it, I fixed this problem

Maybe because some of the resources on your page are not transferred over HTTPS, Apache’s default web page is marked as not safe because of the images inside it try to remove them then refresh to see the results.

Hope this helps.
