Central Web Auth Redirect not working for iPhone/Apple devices

[Chris Terry]

We're running ISE 2.6 and two 5520 WLCs running 8.5.151.0 in a foreign/anchor setup

I'm running into an issue with iPhone/Apple devices not redirecting to the CWA portal. Android devices and a Windows laptop I was using to test get redirected without issue. I can see in ISE that the iPhone is getting the redirect URL to the ISE portal that has a public signed and validated cert. I can also see the iPhone getting the redirect URL in the WLCs as well.

When I open up Safari and type in 1.1.1.1 it will redirect to the CWA portal, but it will be a blank page saying Safari cannot display the page because it's not connected to the internet.
