Our Apple iPhone users having iOS version 15. x are experiencing the "no internet connection" error message while connected to the on-campus BYOD SSID. However, the internet keeps working while the error message is on the screen. This is not happening to prior iOS versions nor any other operating systems including Windows, MACOS, and androids.
This has started happening after we recently upgraded the Radius and HTTPS certificates on our Clearpass servers. These are 3rd party certificates issued by public authorities.
If anyone has experienced any such issue with your environment? A snapshot of the error is also attached.
ClearPass OS Version: 220.127.116.11609
