NCOB02107 - AP's unable to join controller

[davariganesh1994]

Hi All,

Facing below error issue while onboarding AP's to DNAC controller 

NCOB02107: Executed Workflow Timed out. AP didn't join the controller. Please check connectivity/configuration to fix the issue.

This indicates that your access point is unable to join your WLC for some reason. Are you 100% certain that there is no connectivity issue between your AP and your WLC(firewall rules, port auth etc)? Can you see anything in the logs of your WLC?

Hey Torbjon, 

Connectivity from AP to WLC seems fine. From log on DNAC and AP, AP receiving the PNP config and starting CAPWAP discovery, but getting stuck.

On DNAC AP onboarding is getting completed 80% and after around 1 hrs. its giving error.

If we use external power injector its working fine.

Could you please suggest how we can upgrade the AP's before starting joining to DNAC/controller ?
