200.14.6.1.179 to 200.15.6.12.304 causes some Macs to "(code 2) Failed in association procedure"

Hi, everyone.

I have a Ruckus Unleashed network with 4 APs that were upgraded from 200.14.6.1.179 to 200.15.6.12.304.  After that upgrade, several modern Macs (M1 chipset, latest OS) were unable to connect. Unleashed diagnostics reports this cryptic error "(code 2) Failed in association procedure".  Forgetting networks on the Macs, confirming passwords, etc., nothing worked.  Downgrading the network to 200.14.6.1.179 did work, and those same exact machines can now associate with no problem.

Any advice on how to address this?

Thanks!

Hi @jamesb123 

Can you try disabling the 802.11r setting on the SSID and see if it works?
If not, could you please open a support case so that we can collect the necessary logs and troubleshoot further?
