OK finally got it, followed some guys instructions which are:

Open multiple tabs, I used 5 on chrome
The keys are posted every 10 mins so refresh 5 sec before like 2:09:55
You will probably not get it at the first time, but one of your tabs might make it to the select region page and then give no keys
If you reload that almost tab, it will now skip the region select step.
So the next attempt those halfway tabs have more chances to get the key just after the reload.
That's how I got mine
Good luck
