The CORS headers need to come from the
api.s-domain.comAccess to XMLHttpRequest at 'https://api.s-domain.com/api/get_query' from origin 'https://dev.s-domain.com' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: The 'Access-Control-Allow-Origin' header contains multiple values '*, *, https://dev.s-domain.com', but only one is allowed.
I am running nginx inside the pool instances
What does the OPTIONS response look like from
https://api.s-domain.com/api/get_query
Access-Control-Allow-Origin is set to ','. Needs to be your domainAfter that change, add_header Access-Control-Allow-Origin https://dev.s-domain.com; I am getting the following error.
Access to XMLHttpRequest at 'https://api.s-domain.com/auth/get_query' from origin 'https://dev.s-domain.com' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: The 'Access-Control-Allow-Origin' header contains multiple values '*, *', but only one is allowed.
Your CORS header seems to be
*, *. You only need *
Something is causing there to be weird access control allow origin header which is the reason that CORS is failing.
