C9800 WLC PKI Cert Renew Error

Hi,

We have been receiving this error on our C9800-CL controller for some time now and not sure what it requires. 

%PKI-2-CERT_RENEW_FAIL: Certificate renewal failed for trustpoint sdn-network-infra-iwan Reason : Failed to get ID certificate from CA server

Does anyone know what this might be related to. Currently our infrastructure and controller does not have any issues and this controller is managed by DNA Center.

 - Note sure if the feature is supported on 9800 controller ; in that context start with a checkup of the controller configuration with the CLI command show tech wireless  ; feed the output into :  https://cway.cisco.com/wireless-config-analyzer/

   Some of these commands may provide insights :
           show crypto pki certificates
             show crypto pki timers
             show crypto pki server

   In the running-config , you can also enable : debug pki transaction  and check logs

   Also check current software version ; compare too : https://www.cisco.com/c/en/us/support/docs/wireless/catalyst-9800-series-wireless-controllers/214749-tac-recommended-ios-xe-builds-for-wirele.html

What is the DNA Center / Catalyst Center version?

Can you run the following command on WLC:

show telemetry internal connection

I see couple of bugs listed with exact same issue:

Jagan Chowdam

/**Pls rate useful responses**/

DNA version is 2.3.5.5-70026, WLC is 17.9.4.

This command doesnt exists at my WLC

show telemetry internal connection

 I did run 

show telemetry connection all

found an Index name and with:

show telemetry internal connection 1795 detail

I got this:

The state is CNDP_STATE_CONNECTED, indicating that the connection was successfully established.

Check the status with the following commands

show crypto pki certificates verbose sdn-network-infra-iwan
show crypto pki trustpoint sdn-network-infra-iwan status

Hi @jaheshkhan ,

I needed to select WLC from Inventory page in DNAC and update telemetry settings using force config push option. Seems this issue occurs after DNAC update

in my case status is active and connection is up.

 

but last fingerprint is showing as failed. similarly like you. so can i try your steps then?

Sounds pretty similar to outputs that I pasted above. I don't work at TAC but I believe you can
