I hosted my static website https://apsarasx.com on Cloudflare Pages with custom domain and added Web Analytics.
But when I visited the website, I encountered a CORS error like the following.
The request header and response header of the data sent to https://cloudflareinsights.com/cdn-cgi/rum are as follows.
It seems that some fields like Access-Control-Allow-Origin are missing in the response header.
Hope to get help from Cloudflare Team.
I and many others have the same problem but for me it is working on 
https://defihq.pages.dev/ but not on 
https://s.siloco.xyz/
Cloudflare web analytics seems to be hard to use. 
This page is hosted on Cloudflare pages: https://s.siloco.xyz/
I’ve enabled Cloudflare web analytics and I get this error:
Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at https://cloudflareinsights.com/cdn-cgi/rum. (Reason: CORS header ‘Access-Control-Allow-Origin’ missing). Status code: 200.
it is working on https://defihq.pages.dev/ but not on https://s.siloco.xyz/
What can I do?
Getting the same issue myself.
Same issue for me, too.
BTW I am using a service worker.
Hello, evenryone.
After I waited for three days without any action, Cloudflare’s web analytics finally works well.
But I don’t know why.
