Hi
we are getting this error from a cisco C9120AXI-E (V07) AP, when talking to our WLC.

The Wireless Software Version 8.10.151.0
Cisco 8540 wireless controller
AP info as follows:
cisco C9120AXI-E ARMv8 Processor rev 0 (v8l) with 1875204/1095208K bytes of memory.
Processor board ID FCW2648Y17P
AP Running Image : 17.6.4.56
How can we solve this? Our Wireless controller software seems to be incompatible with the software on the C9120AXI-E (V07) AP AP.
