Is that with Instant APs? Or controller based? I assume the first as controller based APs don't communicate to central.
The APs are running recent firmware?
I would run a Wireshark/tcpdump on the traffic to your Airwave (or from an AP that has issues) and see if the TLS setup/negotiation shows something interesting. But it may be better to have a look together with TAC as they are used to read packet captures or they have other methods to find what's wrong.

Hi Everyone,
