Older messages in community (older OS) indicated this error was due to an expired root certificate in Keychain. That doesn't appear to be my issue or I'm missing something. Anyone else having this issue?
MacBook Pro 13″, macOS 13.4
The message indicates some part of the webpage, or the entire webpage, is using an insecure (HTTP) connection, not a secure (HTTPS) connection.
Webpages can be complex and with parts loaded from many different servers, but some part of all that is using HTTP and not HTTPS.
It is preferable that all parts of a webpage use HTTPS, as otherwise sensitive or private data or passwords can be exposed.
Here is how to disable the warning: Change Security settings in Safari on Mac - Apple Support
The preferred solution is for the webpage maintainer to fix the webpage.
This is not related to an expired root certificate in Keychain.
macOS 13.7.4 is current.
Working one day and not working the next arises across an immense range of failures.
And with caching servers and content delivery networks, and with ad networks, there are permutations galore.
A web inspector can potentially identify the culprit reference, if you want to investigate a particular website.
Thanks for your feedback. Your explanation may in fact be the issue, but one day it was fine and the next it was not. I typically use Chrome, not Safari. But I get the same error in Safari as well.
