"lolesports/rewards" Doesnt work.Help

Either im stupid or riot's website doesnt work at all . I've been trying to log in with that link since yesterday and everytime i open it its just a black page with nothing on it . At this point i want to know wheather ill ever be able to complete this dumb mission or not. I mean i liked watching some LCS games in the past but if im gonna be lied to i'd rather stop watching the LCS alltogether
