Hi, I have 2 or 3 working APs that I deleted from one wireless controller and tried to setup on our other controller. The second controller seems to be having some trouble with them. I can see connection attempts but controller isn't setting them up, I see a lot of messages like this one in the logs: Component: RU Session Manager Log Message: Wireless AP registration and/or authentication failed. (AP SN 11330364235P0000 AP IP 172.16.0.6 (active tunnel)) Can anyone suggest what might be happening, other APs I've moved over on the same connection are working fine. Thanks.
