Cisco WLC 4400 Apple iOS 10.2 captive doesn't work

[CSCO11124242]

Good afternoon,

We are trying to setup L3 Web Authentication for the one of our SSID on WLC 4400 which is running latest 7.0 configuration and it works fine for all devices, except iphone 7 with latest IOS 10.2 (probably it will not be depended only on iphone, raise on IOS version)

I know that similar issue present on 5520 controllers, thus I'm wondering if there any workarounds to get such setup working?

Thank you.

Issue is that once apple device is being associated with SSID, open a browser and being redirected to 1.1.1.1 for authentication apple device disconnects from ssid, while WLC still see it as associated and dissociate only by timeout in some time.

I can't provide logs now, but logs looks ok, we are WEBAUTH_REQ state and client is shown as associated. Also I see that apple is trying as usual connects to the captive.apple.com and retrieve hotspot-detect.html
