Calendar app shows the ! in a triangle icon at the top left next to the + above the date. Clicking on the icon yields the above message. Tried a few methods listed for getting rid of "can't ID server" messages, but they haven't worked. Thanks.
MacBook Air, macOS 14.2
I had the same issue, and it was related to a public calendar that I'd subscribed to. The calendar in question had that same ! in a triangle icon next to it. Issue resolved when I unsubscribed.

Calendar can't verify the identity of the server "www.stanza.co"
