         - Tx , for those versioning info's ; reminder these actions are currently strongly advised and useful :
   Have a checkup of the 9800-CL controller  configuration with the CLI command show tech wireless and feed the output to : Wireless Config Analyzer

Can you share WLC Version, AP Model.

AP Side:

Console into the AP and share the complete AP boot log.

WLC Side:

Have you set up trustpoint on 9800? Check with "show wireless management trustpoint" command. 

Look at Dealing with trustpoints section from this config best practices document.

Check this link for "Troubleshooting AP Join" process in 9800 wlc.

How do it ?

 

 - Log into the controller with command line (CLI) not web interface and on the command line issue the command :
                        controller#  show tech wireless   
   save that output into a file and past the content of the file into https://cway.cisco.com/wireless-config-analyzer/

AP is joined sucess thank for help

@lisavbedt for the benefit of all in the community you should share what the problem was proven to be and what the solution was?

That way the next person with the same problem may see your answer and resolve their issue without having to repeat the same question.  The community is about getting help and also helping others.

There is no 17.14.1

The latest version available is IOS XE 17.13.1, but I prefer to stay with 17.9.5.

Did you get a chance to look at the trustpoint as well as the AP boot log.

trustpoing sees healty

  - Sorry but that's not informative enough , run the WirelessAnalyzer procedure as I mentioned earlier and post or attach it here  ; if needed let another IT-person assist you with that ,
