Aruba - guest WiFi users stuck on securelogin.domain.com

I have inherited an Aruba setup which is showing some strange behaviour.

There is a guest SSID which is authenticating with clear pass guest. After the users reach the captive portal and enter their email address they are meant to be redirected to the public website of the company, but instead they are getting stuck at securelogon.domain.com and given a message that the URL cannot be resolved.

Now what is very strange is that this is not happening for all users, and not at all sites. To begin with when this came to my attention we were able to resolve by moving the ap-group to a different controller, but now it seems to be happening with a random subset of users/sites regardless of which controller they are on(we have a cluster of 4 wlc's)

Any idea where I can start looking or how to trouble shoot this? I have a TAC case open but it's painful to say the least.

I can provide more specifics on the setup when required
