I have a radius server running on server 2012r2 and unifi controller 6.0.41 on ubuntu server 19.10
When the controller updated to 6.0.41 my radius wireless network would not authenticate anymore? I checked the radius profile and shared key. Everything looked fine. End devices were presented with the certificate when trying to connect and then would just sit there and spin (iphone, and macbooks). When it wa doing that I would click the blue ! next to the network to get details and it would have a valid ip from the dhcp server. Macbooks would just spin and never connect. Unfortunately I do not have any logs files form the controller. Just curious if anyone else has experienced the same type of issue? Time wasn’t on my side so I restored the controller back to 5.13.29 and everything was fine again.
