CAPWAP State: DTLS Teardown

Hi all,

I'm facing strange problem with one of our sites, AP's are constantly disconnecting from WLC. They are associated for some time, than for some reason they disconnect and enter dtls loop process, they are stuck in loop for some random time (sometimes 2-5-10 hours, there is no rule) then they join WLC and after some time (again, no rules) disconnect. All other sites works like a charm.

WLC is running 8.5.140.0 image and all APs are 1852. Logs from WLC and AP are attached, I did a debug on AP as well. Reboot and factory reset didn't help.

I think that problem is with WAN link, there is some delay that is causing this issue. Is there some kind of timers that can be modified so that capwap discovery process last longer?
