AP 1242AG can not register on WLC 4404

[Alex Nikolaev]

Hello!

I have few Cisco 4404 WLC controllers with 1242AG connected and 2 WISM 1. Everywhere is 7.0.252.0 software and country set as Russia Federations (RU). When I update WLC 4404 to 7.0.252.0 software version no one AP's can not register on controller. The error is 

failed to find matching cert.

No AP entry exist in temporary database

 but when I try to connect AP to wism - all work good. What I do wrong?
