after a crash Safari reports "This connection is not private"
After a power outage and restart, Safari on my Mac mini (Sonoma 14.4.1) now reports "This Connection is Not Private" for nearly all websites I try to visit, all of which were no problem before the crash. In some cases Safari reports it couldn't establish a secure connection to the server. Additionally, Mac Mail now shows question marks where images are supposed to be in messages. I've tried:
1 - Restart Mac
2 - Making sure Time and Date are set correctly
3 - Removing System.keychain and restart
4 - Disabling all extensions in Safari
5 - Clearing History and removing all website data in Safari
6 - Using Private mode in Safari
7 - Restart router (even though other computers on that router are fine)
Multiple restarts of Mac, Safari and Mail, and the problem persists. All was fine immediately before the power outage/reboot.
BTW, if I log out and log in as a different user on the Mini, I get the same results. So it's not something specific to this one account.
Suggestions appreciated!
