Guest access not working after 9.7 upgrade

[it_registration]

After my upgrade to 9.7 Guess pass/ Guess access no longer works. When connecting to the guest SSID it connects but the authentication web page fails to load.

Upon trying to access external outside resources via web browser I get a redirect as expected but it redirects to here:
http://zonedirector.companyname.com/u...

This doesn't work so well.

If I type in the URL it also fails. If I type in the IPaddress/guestpass it works for one of the IP addresses (I'm running smart redundancy on my 1100's).

For troubleshooting steps I've failed over to the other ZD (to change primary) - no change. I've also rebooted both ZD's - no change.

Any suggestions?

Anyone else encounter this?

Thanks

Had the same issue on about 4 ZD1100's all running different versions of firmware 9.7 - 9.10.  Firmware upgrades alone didn't make a difference and neither did a factory reset and restoring from backup.  I had to do a factory reset and configure the ZD from scratch, not ideal solution but gets the captive portal redirect working again.
