Discovery response from 'Hostname' running version 17.3.4. is rejected

[robertjulian]

From AP:

cisco C9120AXI-B ARMv8 Processor rev 0 (v8l) with 1875204/1065904K bytes of memory.
Processor board ID FJC26381AZT
AP Running Image : 17.6.4.56
Primary Boot Image : 17.6.4.56
Backup Boot Image : 0.0.0.0
Primary Boot Image Hash:
Backup Boot Image Hash:
1 Multigigabit Ethernet interfaces

Controller:

Cisco Catalyst 9800-40 Wireless Controller
17.3.4c

My thoughts were that the controller was supposed to downgrade or upgrade an AP if the versions did not match to match the controller.  Is that not how this works?  Or do I need to update the controller to match the 60 AP's we just bought?

This question really isn't Jamf Pro related. Try asking in a Cisco support forum.

5. Logs and Documentation: Review any error logs or documentation related to the discovering tool and the host for more specific information on why the response is being rejected.
