Apple devices are unable to load the portal page or login

Certain versions of Safari on iOS do not properly handle the login form for the Captive Portal page. The most common resolution is to disable autofill for forms in Safari on iOS.

In some cases, Apple devices will not automatically prompt for a Captive Portal login or test for its presence if the wireless network uses encryption. In these cases, manually open a browser and navigate to an HTTP site to get the login redirect.

There have also been reports that on older version of OS X, a Mac would refuse to load any HTTPS sites, including an HTTPS portal, until it could load a CRL and OSCP URL for the certificate. This has been fixed in current versions of OS X.

Some users have had to add www.apple.com to their allowed hostnames so that Apple’s call to their test page succeeds.
