I use FD for our backend API and it's a strange behaviour happening. with some protected networks , we get CORS issue.

"access to xmlhttprequest https://xxxxxx.azurefd.net/api from origin https://xxxxxx.com blocked by cors policy : response to preflight request doesnt pass access control check : no 'access-control-allow-origin' header is present on the requested resource."

I get this error only with protected network.i tried t disable the WAF and yet still same issue. Is there rule engine need to be configured ?
