Chrome Browser Error: Attestation Check for Topics on https://pagead2.googlesyndication.com/ Failed

If you encounter the "Attestation check for Topics on https://pagead2.googlesyndication.com/ failed" error in the Chrome browser console, it indicates an issue with the Permissions-Policy header related to the experimental browsing-topics feature.

Solution 1: Set Permissions-Policy Header

To resolve this error, you can set the Permissions-Policy header to disable the attestation check and the Topic API.

For .htaccess File:

<IfModule mod_headers.c>
Header set Permissions-Policy "browsing-topics=()"
</IfModule>

For Node.js (Express):

const express = require("express");
const app = express();

app.use((req, res, next) => {
    res.append('Permissions-Policy', 'browsing-topics=()');
    next();
});

Solution 2: Disable Browser Extensions

Sometimes, browser extensions can trigger this error. Try disabling extensions to see if it resolves the issue.

Solution 3: Experimental Feature

The browsing-topics Permission-Policy is still in the experimental stage, and most websites have not implemented it. This error can occur due to the lack of support for this feature.

Solution 4: Update Chrome Browser

Ensure that you are using the latest version of the Chrome browser. Updates often include bug fixes and improvements that may address this issue.

In Conclusion:

By setting the Permissions-Policy header, disabling browser extensions, or updating the Chrome browser, you should be able to resolve the "Attestation check for Topics on https://pagead2.googlesyndication.com/ failed" error. If the issue persists, consider contacting the website administrator or reporting the issue to Google.
