We did not encounter this popup recently. However, I’ve found a similar complaint on Reddit:

How To Fix Cannot Verify Server Identity On iPhone and iPad
This error has been covered by us a couple of years ago, as it was mostly caused by the Gmail app (imap.google.com) for iOS and iPadOS.
Other popular apps triggering this error have been Microsoft Outlook (outlook.office365.com) and Hotmail (m.hotmail.com).
However, in iOS 16 affected iPhones and iPad seem to get the Cannot Verify Server Identity error for smaller apps like, that are most likely outdated and haven’t been updated by their developers for a long time.
In the Reddit thread mentioned above the user complains about domain rituationscardb.info been pointed out by the popup. The affected apps are trying to communicate with their server while the certificate attached to it has expired!
