CORS on CloudFront

0

Yesterday my app went down since I started getting "[Error] XMLHttpRequest cannot load https://d9rnb4peo8bk4.cloudfront.net due to access control checks. [Error] Failed to load resource: Preflight response is not successful" Something changed? Ny ideas how to fix it, CloudFront setup to allow CORS and was working fine. Any ideas?

Hi, have you checked the response of preflight request ? The preflight request might received a 4xx or 5xx error. It is common that the error message does not include CORS response headers and browser blocked it for security caution.
