we are integrating Co-browsing in our application. Our application is loading style sheet from the centralized server(CDN) with-in our network. after started co-browsing session the agent is not able to see the screen properly, style sheet were not loaded in the pega dashboard(agent view). But if i copy the style sheet files from the CDN and put it in the application virtual directory then everything works fine. we tried different options like enabling CORS on CDN server and added "Access-Control-Allow-Origin" as "*" in the response header but nothing worked out, Please refer the attachment for more details.

any body have any idea to overcome this issue?
