SecureConnect configured on AP Switchports not working on every AP
I've configured about 50 AP's (MR44) on Switch Ports of several Switches (MS225-48FP). First powered the APs on with Secure connect disabled and every AP works fine.
Now I've tried secure connect enabled (every Switchport has the same FW and configuration). After a few minutes 11 AP Switchports have a green symbol on the Dashboard (AP authenticated with Secure Connect), 39 AP Switchports fails and the Ports are in a restricted state (AP authentication failed using Secure Connect.)
Power cycle the ports doesn't help as well rebooting the switches.
Does anyone has an Idea to solve the problem with AP authentication using Secure Connect feature ?
firmware on all AP's are 28.5, Switch firmware all on 14.32. There are no pattern. On one switch are all 4 AP's running with secure connect working, on other switches 1-2 AP's (the other 10-15 AP's are not).
