AP R760 not discovered by vSZ

[NoiseUnit]

I've a vSZ and an AP, on the same vlan (management).

First curious problem, the AP has not been able to get a DHCP ip address. 
Then I manually configured an IP on the AP and, my AP and my vSZ are able tto ping each other, as ther are able to ping the internet or local dns addresses.

I did manually enter the "Primary Controller Addr" in the AP Administration/management configuration, with no success. Also, I did create a DNS entry for ruckuscontroller.something.com and zonedirector.something.com. I also tyring with the DHCP option 43.

I did a pfsense firewall, but there is no specific rules for this vlan, all traffic allowed. My AP is on a trunk, management vlan is untag and the others are taged.

The fact that the DHCP is not working in the first time is still bugging me, but I can't see the reason for all this.
Please advise. Thank you.

My R760 is now online inside the vSZ !!!!!!
My R560 is not, but I'm assuming I must be on the good path or something. 

(still, any advise will be warmly welcome, thank you!)

Alright. I've been able to see a R560 in my vSZ as well. I assume I can consider this ticket as resolved. Thank you very much to both of you!
