vWLC and ISE. vWLC service port down. WebUI can not be accessed.

Hello, randomly i can't access my vWLC by WebUI and also all clients on Dot.1x losing connection and can't re-authenticate. Non dot1x clients staying with network. This problem appears with low and high utilization in network at any time. I can access my vWLC by ssh on management port when service port down. 

I have couple of errors from syslog:
 Message: *Dot1x_NW_MsgTask_0: Feb 28 10:41:18.230: %DOT1X-3-INVALID_REPLAY_CTR: 1x_eapkey.c:451 Invalid replay counter from client xx:xx:xx:xx:xx - got 00 00 00 00 00 00 00 03, expected 00 00 00 00 00 00 00 04

Right now i don't have syslog from end to end when disconnects happens. I'm trying to collect it. 

I can't find reason why service port going down. I did not configure this system so i think maybe is there issue between Cisco ISE and vWLC, where ISE somehow disables interface on vWLC?. SNMP not enabled.

When i google this i found that when somebody writes sh port summary there's at least 2 interfaces showing. I have only one

Another question: In ISE wlc configured with Service port is it right or need to be management?

Okay i probably found a problem. if I understood correctly maybe ISE Device Profile disabling wlc interface by SoA. Is there any way do debug why it sending disable port ?

Okay i found that CoA on wlc and Ise enabled but "show radius rfc3576 statistic" all counters are zero.
