AP rejected on vSG "because of ACL setting"
I am unable to add multiple R600 APs at a remote site to our vSZ. I'm moving them from a local (to them) ZD to a remote (central location) vSZ, but the procedure I've used many times no longer works. I factory defaulted the AP, then "set director ip xxx.xxx.xxx.xxx" and rebooted, and it does contact the vSZ, but the controller is rejecting it with this error:
ZD-AP [obscured] model [R600] is not being upgraded with Virtual SmartZone AP firmware because of ACL setting."
I then tried upgrading the AP to 100.x standalone firmware, but same results... it gets rejected with that error. Any idea what is wrong? I've added APs from remote sites with no problem, so this is a first for me.
