Default [Q] VS980 OTA Unavailable?

I have a VS980 and it was running on CM11 few days ago. However, I decided to revert back to stock yesterday. The problem I have is that when I revert back to 11A through TOT flash, I can't get the 12B update anymore. The ota was fine maybe a week ago on my device. Does anyone have the same issue? Is it possible they shut down the ota server just for incoming 4.4 update since ATT version got their update earlier today?
