The immediate solution is to manually approve that site’s certificate, which bypasses the expiry of its other certificates. Step back to the Root Certificate, and you’ll see that’s due to expire on 30 September, the very next day. The first certificate to expire was the intermediate R3, which expired on 29 September, a day earlier. In this case, the site’s certificate remains valid until the end of this year, but the intermediate certificate R3 has expired.Īlthough this is a Let’s Encrypt certificate chain, the first of the certificates to expire wasn’t its DST Root CA X3 which we were warned about, which remained valid at the time that this happened to me.

That Safarian error message means that it tried to connect using HTTPS, and has detected a certificate problem. You try to connect to an affected website using Safari, only to be informed that This Connection Is Not Private. And there’s more than one certificate which has now expired.
