How to change app domain into to the test?

I have used app domain on my laravel projects till today, but today mozilla starts open app domains with `https..

So I edited my laravel.app.conf file and changed Servername as laravel.test then restart my apache2

sudo service apache2 restart

But this time local website doesn't open, it says server not found.. Did I something wrong ? Or am I need to do something else ?

Edit: Also I changed /etc/hosts file too
