Refused to frame 'https://pagead2.googlesyndication.com/' because it violates the following Content Security Policy
I have adsense implemented on my webpage, but sometimes when I load the page I have the following error message printed in the console when loading the webpage with ads, and it doesn't happen every time, but mostly the error appears.
Related to:
Content Security Policy (CSP) Error
The error message indicates that the browser has blocked a request to load a frame from ad sites due to a violation of the Content Security Policy (CSP).
Causes:
1. CSP configuration issue
2. Insecure content (HTTP) embedded in HTTPS page
3. Frame-ancestors directive mismatch
4. Google AdSense configuration issue
CSP Directives:
1. frame-ancestors: specifies allowed frame ancestors
2. frame-src: specifies allowed frame sources
3. child-src: specifies allowed child sources
Solution:
1. Update CSP configuration:
- Add frame-ancestors to allow Google AdSense frames.
- Add frame-src to allow Google AdSense frames.
2. Ensure HTTPS content:
- Verify that all content, including ads, is served over HTTPS.
3. Verify Google AdSense configuration:
- Check AdSense settings for correct frame-ancestors and frame-src directives.
