Found the API Links in class-wow-armory-character-dal.php
Updated the API Links and added my APIKey but still got error. After removing variables and set a static link, it works, but only for that static character.

https://%s.api.battle.net/wow/character/%s/%s?fields=guild,items,professions,talents,titles,achievements,feed&locale=de_DE
