On the other hand, you made an https request to cgisecurity.net but presumably got (and accepted) an ssl certificate for selenium.qozzy.net.
This is likely because cgisecurity.net is not configured as a https site here, and so the server instead presented you with the first matching host on the same IP address as the site you were going to.
This is unfortunately a side-effect of the way the web server figures out which site to give you.
Now that you know this, you will probably want to go somewhere else.
