Since installing 10.15.6 supplemental update on Friday, I cannot browse to any web sites using HTTPS, and even MacOS Software Updates reports an SSL error. Internet was working until 10.15.6 supplemental update. Nothing on my network has changed.
This on an iMac connected to internet over WiFi.
I've removed all expired certs, rebooted multiple times.
Did you try booting to safe boot and try the download and install(?)

Takes noticeable longer to get to the login screen, does a 5-15 minute disk repair before it fully boots up, and certain system caches get cleared and rebuilt, including dynamic loader cache, etc. Login and proceed

I tried Safari, Chrome and Firefox. All give the same error.
I am not using a VPN.
This is a problem with the update. There have been no other changes to my system. The update changed some setting or is causing some other config setting to be ignored. This problem is at the OS / network stack level.
Rebooting in Safe Mode allowed internet connection. Problem ended up being with 3rd party software extension, Covenant Eyes. Got an update from them and all is well.
