WGB cannot authenticate to network after WLC firmware upgrade

[l.buschi]

Hello,

I have a mesh network working with 3504 WLC and Firmware 8.5.X.

On this network I have associated some WGB made with standalone APs (1262 and 1242) authenticated with WPA2 - PSK.

This is my standalone ap configuration:

dot11 ssid xxx
authentication open
authentication key-management wpa version 2
wpa-psk ascii 7 xxx

interface Dot11Radio0
no ip address
no ip route-cache
!
encryption mode ciphers aes-ccm
!
ssid xxx
!
antenna transmit right-a
antenna receive right-a
station-role workgroup-bridge
mobile station scan 2412 2437 2462
mobile station minimum-rate 11.0
mobile station period 10 threshold 80
bridge-group 1
bridge-group 1 spanning-disabled

this APs perfectly work with 8.5 release and don't work with 8.10.X 

My rap and map APs are AIR-AP1562E-E-K9

Air-ap1242 are use as standalone access-point with wgb role.

No particular restrictions can be found
