[Thanks, that's exactly the failure the check was written for. The renewal job reports success, the file on disk is new, and the process still holds the old certificate in memory until something reloads it. The renewal log can't see that gap, which is why we compare from the outside. One small addition: check the full chain the server presents as well as the serial. A renewal can also swap intermediates, and a stale chain fails for some clients even when the leaf is correct. And yes, with shorter lifetimes coming, an outside check that runs on a schedule beats remembering to look.](https://hashnode.com/posts/will-your-tls-certificate-renew-and-reach-your-visitors/6af1dd4ef94bf79c94398830/comment/6af1f42c3fc61c9cdfaefd75#reply-6af1fc3180a0cf41de3b4a2a)

[Thanks, Damiano, that's a useful extension. You're right that \_\_Secure- still requires the Secure attribute and a secure origin but allows Domain, so a cookie scoped to the parent domain is sent to every subdomain and each one becomes part of the trust boundary. Checking for dangling DNS records on subdomains you no longer run is a good addition to that case.](https://hashnode.com/posts/session-cookies-7-checks-for-secure-httponly-samesite-and-logout-and-what-a-pass-doesn-t-prove/6ae97dc57ca8e63fee07885b/comment/6ae9b473df2fb62ef87d1360#reply-6ae9b5fedf2fb62ef87d2033)
