Make sure that your feed is accessible from our static IPs.Configuration can vary depending on your security solution, but generally, you can allowlist the IPs in your firewall or security settings.Only the feed URLs need to be allowlisted, not your entire domain.
Add a check for field “URI Full” to be equal to your feed URL, e.g. https://www.shop.com/google-products.xml
Add a check for field “IP Source Address” to be in the list of our static IPs
Your expression preview should look similar to this: (http.request.full_uri eq "https://www.shop.com/google-products.xml" and ip.src in {35.207.69.21 209.38.162.12})
