I have two controllers, one is 4400 and the other one is 5500. Before the upgrade the redirection was working fine. We have upgraded 4400 to 22.214.171.124 and 5508 to 126.96.36.199.
After the upgrade redirection is working only with 4400 controllers. If we move the AP to 5500 redirection is not working. we are using external web authentication
Please let me know if anyone faced issues related to the webauth redirect.
Thanks & Regards
There are few bugs in 188.8.131.52 code related to webauth, see whether you are hitting one of these.

The page would either error out or client sees the virtual IP address in address bar. Or, browser connection attempts to the WLC GUI time out. Workaround: wait a few minutes and retry.
