i get a 403 Respons.
But i have tried like alot of different login path since it seems to be multiple adresses, byt they all give me the same respons.
So im guessing im getting to the wrong page?

well it beats me since i have no idea to tackle this problem. The code to login should be good since its the same person who has coded the call of duty stats plugin for discord and he has documented the login process here
