As of July 24, 2018, Google started rolling out Chrome 68 and website security has become increasingly important with Chrome 68. Google Chrome gives the error “Your connection to this site is not secure” in the address bar for all websites that are not protected by “https”. In another case, while the browser users want to connect to some sites, your connection is not secure and they are warned by the internet browser that their access to the site is not secure.

The reason Chrome has started to do this is because it wants to encourage site owners to use the more secure HTTPS protocol. As a result of these and various other incentives, there has been a serious leap in HTTPS adaptation rate over the past few years. If you encounter this error, you can secure your site.

It means that website does not use HTTPS as trusted Google Chrome wants to encouroge website owners to use the more secure HTTPS protocol.
