We are having an issue where the guest portal is not bringing up the redirect page for authentication. We are using a Cisco WLC 5500 and use ISE version2.4.0.357 patch 8,11. On this issue, the AP in question is part of a flexconnect group with other APs for the site. ALl the other APs in this flex connect group can connect fine and get the proper redirect page. On the AP in question, all other SSIDs work as well, they are wpa2. This particular SSID is our guest network and uses a guest portal for auth. I was reading online that sometimes the AP does not pull all the correct files, but how can I access the command line of the AP to verify? I would also like to debug the controller for this particular session but dont know what debug would let me see this interaction of client and AP of getting a blank redirect page. I cant seem to telnet or ssh in. Any help or guidance on what to troubleshoot would be greatly appreciated.
