Hi guys

I have lemp stack installed on ubuntu 14.04

i have 2 domains

first one is working perfectly both with "www" and naked url

but for second domain

when i try to reach my website with "www" it shows me blank page

i reach to the website with "www" but cannot reach without "www"

looks like cname is not working
