1006 ERROR - no access to my website

Hi everyone, I’m encountering a recurring issue on my website. It seems to involve an external URL: https://birdy-sec.s3.us-west-1.amazonaws.com. This URL is being loaded dynamically on my site and is causing intermittent access problems, sometimes leading to a 1006 error (Access Denied), which I believe is related to Cloudflare. Key Details: Website CMS: I’m using SPIP (version being updated manually). Problem Description: This URL (birdy-sec.s3.us-west-1.amazonaws.com) is either injected by a plugin, script, or external widget. It's causing the site to break for some users, resulting in an error page from Cloudflare. Users see this error both in their browser console and sometimes as part of the site's response. What I’ve Tried: I’ve checked all local files (HTML, CSS, JS) but cannot locate this reference in my codebase. I’ve added .htaccess rules to block or redirect this URL without success. Server logs don’t provide clear clues about what’s triggering the error. I’m now reaching out to see if Cloudflare might be blocking or interacting with this URL. Questions: Is Cloudflare’s WAF (or any specific rule) blocking this URL or related traffic? Is there a way to identify why Cloudflare is serving this error and how to resolve it? Any insights or guidance would be greatly appreciated. Thank you!
