Access point not showing up under inventory in catalyst DNA center

[DAVID]

I am syncing sites and devices between Cisco prime and DNA center. I have a particular site map and access points that have migrated over with the exception of one AP. Oddly enough, this AP does show does show up and registered to the wireless controller that is in the DNA

             - Reboot the AP and check if that can help ,

 this AP does show does show up and registered to the wireless controller that is in the DNA 

so this joined controller and users able to connect ?

what is model of the AP and WLC controller, what code running WLC and what DNAC Version ?

Take the Serial number and check DNAC ? Take the MAC address of AP and check ?

[DAVID]

Dnac=2.3.5.5

Controller= 5520 8.10.190

AP internal 1815 on Cisco ISR C1100

No clients are connected to missing AP

[balaji.bandi]

Did the AP  joined controller ?

Other AP joined controller and able to see in DNAC same model ?

i would check if  the AP got DHCP and able to join WLC before i go check in the inventory ?

[DAVID]

AP is joined to the correct controller. Other AP's on same site connected to controller and are in map/inventory on DNAC.  

[balaji.bandi]

Other AP's on same site connected to controller and are in map/inventory on DNAC

All are same model of AP ?

DNAC always rely controller to provide that information AP joined WLC.

Try in DNAC resync with controller.

[Haydn Andrews]

Try a re-sync of the WLC with DNAC and restart telemerty on the WLC

[DAVID]

Did a resync between controller and DNA. No changes. Not sure where to restart telemetry service on 5520 WLC. WLC does show telemetry service enabled and connected to DNAC.

how did you search for this missing access point ?
did you use the looking-glass in the upper right corner to search for the (ethernet) mac address ?
did you check the count of DNA licenses for access points?
