Default [Q] why my Nexus not getting any OTA updates?

Hi

I'm using Stock ROM in my Nexus 4. I've never get any OTA updates since I upgrade to KitKat. Every time I check for new software updates it said i'm using the newest version but my Nexus still 4.4.2. 4.4.3 has been released for weeks and I've never get any OTA updates until I update it manually

Now 4.4.4 has been released and my friend who use Nexus 4 has recieved OTA updates. My nexus still not getting any. Is there a problem with my nexus?

I'm from Indonesia btw
