It's almost certainly about the lifetime of the cert. Chances are this certificate was issued for a period longer than 397 days. It's a really misleading error, because there's no "standard" that is in play here, it's an arbitrary apple decision.


According to a document published in August of 2023

And then, in November 2023, they changed this tune, making the requirement 825 days maximum for ALL certs issued after July 1, 2019 (regardless of if it had a private trust anchor or not).

Hi John,


We checked with AWS and below is their feedback


As the same certificate seems to work perfectly fine with other browsers and latest safari version, this doesn't seems to be a certificate issue. This seems to be case of client-side MacOS error.


When I access the same training on other versions line Big Sur and Ventura and the issue was not seen.


Can you please advise

I tried that and we also deleted the cache, yet getting the same error.


I was trying on Big Sur and Ventura with Safari on another machine and did not see this error. The training is working seamlessly on Big Sur and Ventura with Safari.


If it were a AWS issue then this certificate error would happen on Big Sur and Ventura with Safari? why is only happening with the below combination:


Mac OS Monterey Version 12.3

Safari Version 15.4 (17613.1.17.1.6)

Hardware: 2.6 GHz 6-Core Intel Core i7


Can you please advise?
