户端本机选择-副本站点，上传文件没有反应
I am using Windchill PDMLink Release 12.1 and Datecode with CPS 12.1.0.1
客户端本机选择-副本站点，上传文件没有反应，F12报错：has been blocked by CORS policy: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource.
但是在副本的服务器上或者主站点的应用服务器上是可以上传的
Service Contract Number (SCN): 4R2691717
Here are the errors that I faced
F12报错：has been blocked by CORS policy: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource.
