R500 Shows "This AP is currently unable to provide wireless access. To resolve, connect to a Ruckus Controller. "

unknown

Having turned on our vSZ after it laying dormant for many months due to another issue, the one AP I left configured to it shows a message saying "This AP is currently unable to provide wireless access. To resolve, connect to a Ruckus Controller." when I log in to the Web UI of the AP.

The vSZ sees the AP and says that its connected and will recognize when I turn it off and on but the AP is not broadcasting any WLANS.

I have a theory that this might be due to the certificate issue that was noted a while back but am unsure of how to more towards a solution.

Can anyone point me in the right direction?

Thanks
