Can't log in via google account to pre summon event

[mossy hornet]

Hello i play in German. If i try to log in to the pre summon event i claims me an unsafe website, on pc steam client or android gameclient. Doesn't matter. If i log in via Facebook it works but then i don't have any summons. If i am logged out it claims me 40 summonsto try.
I now try it via webclient on the Browser linked to the pre event registersite.

ok, i now used the firefox webbroswer and could log in via google. then also could claim the rewards of the quests

i now try my luck with summon
