I have multi store as well as multi domain in my magento site.
the issue occurs in back-end (admin grid) when I want to filter products, orders, or customers.
the error says
Access to XMLHttpRequest at 'https://www.domain.be/admin_12w5st/mui/index/render/key/' (redirected from 'https://www.domain.nl/admin_12w5st/mui/index/render/key/a65af72908ae41562210df6cbc370a9bf0d4ce996237d2a40aec7804fa8d3673/?namespace=customer_listing&search=&filters%5Bplaceholder%5D=true&filters%5Bentity_id%5D%5Bfrom%5D=1&filters%5Bentity_id%5D%5Bto%5D=2&paging%5BpageSize%5D=20&paging%5Bcurrent%5D=1&sorting%5Bfield%5D=entity_id&sorting%5Bdirection%5D=asc&isAjax=true') from origin 'https://www.domain.nl' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: Redirect is not allowed for a preflight request.
here are my environment :
- magento 2.2.9
- php 7.0.33
I tried to put
add_header 'Access-Control-Allow-Origin' '*' 'always';
or without quote mark
add_header Access-Control-Allow-Origin *; in my server.headers file but still no luck, the issue still persist.
Does anyone have any idea? Thanks in Advance.
