You must select the top level certificate.Д®nter your user account password to grant access when prompted, NOT your Backblaze password. Select вЂњISRG Root X1 CertificateвЂќ from the hierarchical list. I have succesfully tested it on 2 different environments, and it is working.Д¬lick вЂњShow CertificateвЂќ in the window that opens. Note that you could also use for fetching the ISRG ROOT X1 certificate. I had clients with similar problems, and clients with backupsoftware from Backblaze that was having issues.Д«ackblaze provided this solution. Trying to find a solution I ended up at your site and this article. Whether youвЂ™re running a server which relies on LetвЂ™s Encrypt certificates, or trying to connect your browser to one, the most helpful and information page on the subject is this one from Certify The Web. No thanks to LetвЂ™s Encrypt, which seems unaware that any of this might cause such problems. Emptying SafariвЂ™s caches doesnвЂ™t help, as I think the old certificate information is held in a separate security database to which the user has no access. What can you do about this more generally, to save you from having to make each broken site an exception? As far as I know, nothing that youвЂ™d want to.

My M1 Mac mini had never connected to that site, so had to perform a fresh check on the chain of trust, which then traced back to the current chain with its replaced intermediate and Root certificates.

Both my iMac and iPhone have connected to this site previously, and rather than performing a full certificate check every time, macOS is just using old results, which still refer to the old intermediate and Root certificates.

The answer I suspect lies in the caching of certificate checks. So how come two different Macs connecting to the same site get such different chains of trust? The intermediate certificate R3 here has an expiry date in 2025. 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.
