No AP manager addresses/no valid AP manager found

[tyler.perkey]

Hi All,

I'm trying to connected an 1831 AP to an eval version of vWLC 8.x (I've tried multiple) and keep getting this error:

No more AP manager addresses remain..
[*12/15/2020 16:02:01.8307] No more AP manager addresses remain..
[*12/15/2020 16:02:01.8307] No valid AP manager found for controller 'WLC' (ip: 10.0.0.99)
[*12/15/2020 16:02:01.8307] Failed to join controller WLC.
[*12/15/2020 16:02:01.8307] Failed to join controller.
[*12/15/2020 16:02:19.9550] Restarted PnP Discovery timer after time sync for 90 seconds

The AP joined 1 time running 8.10, updated it's image then wouldn't connect again.

Everything is on a flat network, it finds the controller, NTP is set.  I can't find any reason it does not connected to the controller.

Pls try "capwap ap erase all" command on AP CLI

I just discovered the problem, my management port and service port being on the same network was causing some conflict.  When I disabled the service port network adapter in ESXi the AP joined properly.

Good to hear that...
