I have a sub domain subdomainA
and a main domain mainDomain both points to the same server and same source.
I am facing the following issue when calling the api of main domain from the sub domain url as below:
Access to XMLHttpRequest at ‘MainDomain’ from origin ‘subdomainA’ has been blocked by CORS policy: Response to preflight request doesn’t pass access control check: It does not have HTTP ok status.
I have tried all the suggestions so far but could not fix the issue.
Anybody please guide me to fix this error ?
