Error code: 0x8004FC12, can't activate

So I installed windows 10 a week back and was successfully able to activate it. After doing that, I did a clean install and was again able to activate it. Today, I had some problem with my computer not beeing able to find my wifi adapter, so I reinstalled windows 10 which solved that problem. Now however, I am not able to activate windows again. I get the Error code: 0x8004FC12. I've tried activating via the phone and the command prompt, neither has worked. Anyone facing the same problem or have any solution?

**UPDATE**
I just restarted my computer for an windows update (Cumulative Update for Windows 10 for x64-based Systems (KB3081424)). Once complete, I was able to activate windows on my first try. I don't know if the update had anything to do with it or if it just was happenstance (I had tried multiple reboots earlier with no results).

The problem will have been the activation servers will have been busy when it tried first. Not unusual.
