Ruckus Unleashed R320 - AP's trying to become Master and rebooting every 5 minutes

unknown

I have 3x Ruckus Unleashed AP R320 connected to a Cisco POE Switch and a Wifi Router.

AP's get IP from the Wifi Router's DHCP 

I updated the firmware two days ago and since then the the members AP's are trying to become Master AP and reboot every five minutes. 

Things I have tried and did not work for me:

Factory reset
Restarted the POE switch
Assigned priority to master 


I think the Member AP loses connection with Master AP and tries to become a Master and then finds the Master and reboots and this cycle keeps going on..

Any thoughts?
