Standing up a 9800-CL wireless controller.
Got through the initial deployment, the Day Zero config, and can log into the WLC, but I cannot get my AP's to join it.
AP models are 1832 and 3802.
Tried WLC versions 16.11 and 16.12, both with the same results.
I can ping the WLC from the AP, and I can log into the GUI fine from my PC.
My AP's can reach the controller, but keep dropping the DTLS session when they try to join.
Here's the output from the console on the AP:
[*11/18/2019 22:08:20.0122] CAPWAP State: DTLS Teardown
