Some clients can't web authenticate - page doesn't load
We've got two SSIDs - one is a Guest network, one is an open network with Web Authentication (against AD) turned on.
When devices connect to either of these, some are presented with a login box or guest pass box, depending on the SSID they connect to.
However, a lot of users are reporting that they don't get this far, they get a "page cannot be displayed" or similar message, with the URL of the ZD listed in the error.
My Android phone is one giving an error, however it previously worked fine before we "went live".
I've seen the error on Windows Phone, Android and iOS, along with laptops using Firefox or Chrome.
Safari and IE seem to be fine though?
The ZD has a valid certificate generate by our internal CA and we're running firmware 126.96.36.199 build 15 on a ZD3000
