[URGENT] Getting 404 Not found when requesting Auth token

Hey everyone - we're launching a new product @ https://wonderverse.xyz and we're launching on the 20th of June. As part of this launch allow users to add POAPs as rewards as their members complete quests. However currently when I follow the instructions in https://documentation.poap.tech/docs/authentication I get a 404 Not found with my correct ClientID and ClientSecret. Anyone have any clue how this can be fixed? Seems to be a recurring problem https://documentation.poap.tech/discuss/6481e31117a8161481a3de80

Thanks for the help!
