The siteвЂ™s certificate appears identical, although the Root Certificate is different, ISRG Root X1, which is the replacement for the DST Root CA X3 expiring on 30 September. Indeed, it showed a different chain of trust altogether. To answer this, I tried making the same connection on my iPhone (iOS 15), which failed similarly, and on my M1 Mac mini (macOS 12 beta 8), which had no problems at all with that site. However, according to my previous article, this shouldnвЂ™t affect macOS 10.12 or later. Once that has been added, you can continue to access that specific site, but others which rely on the same chain of trust will need to be added individually. Safari will then add a special certificate to your keychain for that particular site. The immediate solution is to manually approve that siteвЂ™s certificate, which bypasses the expiry of its other certificates. Step back to the Root Certificate, and youвЂ™ll see thatвЂ™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 siteвЂ™s certificate remains valid until the end of this year, but the intermediate certificate R3 has expired.ДЄlthough this is a LetвЂ™s Encrypt certificate chain, the first of the certificates to expire wasnвЂ™t its DST Root CA X3 which we were warned about, which remained valid at the time that this happened to me. If youвЂ™re happy that doesnвЂ™t explain the problem, click to view the certificate. You might wish to use another browser like Firefox to check the website out before making any decision, then clicking on Show Details to proceed further in Safari.ДЇurther information provided by Safari is helpful, explaining the certificate expiry, giving that date and inviting you to check your MacвЂ™s clock. The solution depends on your confidence that the error is spurious, which depends on how much trust you can put into that address and site.

It may appear sporadic, although once it has affected a site, Safari is unlikely to be able to make that connection properly again.

This can affect any (reasonably recent) version of Safari, running on macOS, iOS or iPadOS, and on pretty well any version of those operating systems. 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 thereвЂ™s more than one certificate which has now expired.

Unfortunately, it has turned out that this isnвЂ™t confined to older Mac OS X, and can even affect Monterey betas.

A few days ago I warned that those still using older versions of Mac OS X are likely to have problems making secure HTTPS connections with many websites, because of a security certificate due to expire on 30 September.
