Your connection is not private only on my sites (privacy error)

Question

From time to time, all my websites hosted on one unique web server received this error when I wanted to view them through my computer. it works on another computer (browser)

What is the problem? Have some settings been changed? I googled it, but it didn’t work out for me.

Answer 1

This happens if security certificates are not installed on your website server or if it does not match the root certificate installed in your browser.
