Looks like a Problem with Chrome security.
I have done some searches...
Maybe it is due to HSTS.
If you connect to your wireless SSID you have to open your brower and open a URL.
So could you try to open an unencrypted URL ?
May i know any solution for this issue because i'm having the same as well, if possible to create a self signed cert on WLC will solve this issue at android google chrome browser?
