Page Overlay loads the page that i want to tracking correctly, however with no bubbles in page.
The console log give errors as below:
Refused to frame '<My URL I am tracking>' because it violates the following Content Security Policy directive: "default-src 'self'". Note that 'frame-src' was not explicitly set, so 'default-src' is used as a fallback
Thanks fro your reply.
I have set domain with (Administration > System > General settings), then config the websites( that i want to track) nginx by `add_header Access-Control-Allow-Origin ;`
however, it does not help. When I open the page overlay, it gives the same error still, and the left side keeps on loading.
@topcnm You might need to adjust the nginx content security policy rule to allow Matomo to iframe your website.
I can't give you the exact changes as I don't know your configuration, but it would look something like
add_header Content-Security-Policy “frame-src ‘self’ your-matomo-domain.com”
