I have few sites which did not have `SSL` cert setup. The issue I am facing is, if these sites access using `https` it shows **Unable to connect, Browser can't establish a connection to the server at mysite.com** error

I think it should give a **Your connection is not secure** warning and give an option to go to the site 

I cannot redirect `https` to `http` since there is no connection with the server

Done few searches but nothing shows up other than setting up `https` and troubleshooting. 

I'm using ubuntu server with apache2 installed. It will be great if anyone can advice where to look/start. Thanks!
