We had the EXACT same issue in April. TAC was useless. We just rolled back to the earlier train, 8.5.161 in order to get everyone connecting again.
As we are hoping to move back to the 8.10.X train this summer to get the DNAC benefits again, I will continue to watch this thread.

It is weird because radius isn't even seeing the attempts (or weren't logging rejections). The behavior persists even using local authentication. Eventually we can get the clients to connect, but it takes a number of attempts. It's very frustrating. Cisco had us upgrade to 8.10.122, but the problem still persists. We would roll back, but we have 9130's on the campus now and we need 8.10.122 to manage them. Such a headache right now.
