Common problems
Non-secure main origins
When the main origin of a page is not secure, the Security Overview says This page is not secure.

This problem occurs when the URL that you visited was requested over HTTP. To make it secure you need to request it over HTTPS. For example, if you look at the URL in your address bar, it probably looks similar to http://example.com. To make it secure the URL should be https://example.com.
If you've already got HTTPS set up on your server, all you need to do to fix this problem is configure your server to redirect all HTTP requests to HTTPS.
If you don't have HTTPS set up on your server, Let's Encrypt provides a free and relatively-easy way to start the process. Or, you might consider hosting your site on a CDN. Most major CDNs host sites on HTTPS by default now.
Mixed content means that the main origin of a page is secure, but the page requested resources from non-secure origins. Mixed content pages are only partially protected because the HTTP content is accessible to sniffers and vulnerable to man-in-the-middle attacks.

In Figure 3 above, clicking View 1 request in Network panel opens the Network panel and applies the mixed-content:displayed filter so that the Network Log only shows non-secure resources.
