Não consigo acessar um servidor externo para recebel

Boa tarde, estou com um problema e não consegui resolver de nenhum jeito. Preciso buscar informações para criar um lista.

Tentei todas as formas de access-control, adicionei o plugin whitelist, ajustei meus origins no XML.

Preciso de HELLPPPP. rsrsr

Failed to load resource: the server responded with a status of 405 (Method Not Allowed)
index.html:1 XMLHttpRequest cannot load http://www.santorock.com/api/catalog_system/pvt/category/tree/3/. Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost:8000' is therefore not allowed access. The response had HTTP status code 405.
