Microsoft Edge CORS blocking external web calls on CRM

Question

Hi. I am working on Dynamics 365 CRM.We host external web application in CRM. When I try to access Web pages, it asks for authentication and everything is good.But when i make XmlHttpRequest to call json functions in my Web project, i get this error:&nbsp;"Access to XMLHttpRequest at 'http://{server}:{port}/{org}/{controller}/{function_name}' from origin 'http://{server}' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: It does not have HTTP ok status."&nbsp;I tried to add site in trusted sites n IE and import settings on EDGE&nbsp; from Internet Explorer. Can you please help how do i fix the Issue?I get the same issue on chrome as well. I did not get this issue with Internet Explorer.&nbsp;Thanks.
