Www not working, and without ww is working



I created droplet 16.04 ubuntu and installed wordpress site with letsencrypt with easyengine command
wget -qO ee rt.cx/ee4 && sudo bash ee
ee site create cameraforme.com --wp --letsencrypt

I also edited my domain DNS here is the screenshot https://snag.gy/ViUFMo.jpg

after that https://cameraforme.com is working
but www.cameraforme.com is not loading

please suggest what I did anything wrong or have to edit something. I am a newbie
