"This connection is not private " after installing SSL certificate on apachein ubuntu 16.04

Posted October 16, 2018 5.3k views

hi guys,
i installed the Self-Signed SSL Certificate for Apache in Ubuntu 16.04 using the tutorial

i did this twice but i still get a ugly message in red saying “this connection is not private” and that this website may be impersonating to try and steal personal or financial information.

Though the tutorial says its happens but how can such a message be good for visitors?After i open the advanced option and allow the website to go forth ,i cant load it the way it was meant to.

Please help!Is there something i am missing here?

If not, then i think i prefer to be “unsafe” than have such a horrid message for visitors.

The Common Name should be the same as the exact web site domain to which you are connecting.
In the case of this page where I am posting the certificate common name is

You can check the ssl status if your site by searching google for “Test if my site certificate is ok”
You should find some sites where you can type in your domain and it will report on your certificate status (And usually try to sell you a new one! :-)
