I'm having a strange issue with a 5508 WLC : the http/https access doesn't respond on the management interface but the ping is ok.
I can access the WLC on its service port in http/https.
SSH is ok on the service port and on the mangement interface.
Management interface and service port are not in the same subnet
Stranger thing is that when I enable the SSO to mount the HA with the second controler on site, the service port become also unavailable on http/https ! I have shutdown the second WLC for the moment, and disabled SSO on the active controler to get my http access back.
Unfortunately, I can't upgrade the WLC (188.8.131.52) because it's the last version that support some old ap's i have attached to it (1131 & 1242...)
I have tried many solutions found on the cisco forums and over internet, but nothing can get me the http access back.
Please find attached the show tech-support file if it helps.
