Defect Information


Defect IDHeadline
CSCwh58054EWC-AP: CCO software downloads fail authentication after April 30, 2024

Problem Description


When attempting to perform a software upgrade using "CCO mode" in Cisco Embedded Wireless Controller on a Cisco Catalyst Access Point (EWC-AP), authentication fails. This issue occurs when attempting to upgrade from a software release earlier than one of the following releases:

  • 17.3.x
  • 17.6.x
  • 17.9.5
  • 17.12.3
  • 17.14.1

Background


Beginning May 1, 2024, Cisco Connection Online (CCO, a.k.a. cisco.com) will use a new authentication system for EWC-AP. This system is not backward-compatible with older EWC-AP software.

EWC-AP software released after January 31, 2024 will be able to authenticate to Cisco.com both before and after May 1, 2024. Those releases include the following:

  • 17.9.5 and later
  • 17.12.3 and later
  • 17.14.1 and later

Problem Symptom


If attempting to upgrade using EWC CLI, a message similar to the following will be seen:


EWC-AP#terminal monitor
EWC-AP#wireless ewc-ap predownload poll-cco
*Jan 11 17:03:09.796: %APMGR_TRACE_MESSAGE-3-WLC_EXEC_MSG: Chassis 1 R0/0: wncd: % Error: CCO query for software version failed
WLC70F0.96ED.8400#sh wireless ewc-ap cco-status


CCO Suggested SW Version  :
CCO Latest SW Version     :


Last CCO Response         : HTTP 400 Error: {"error_description":"
We didn't recognize the username or password you entered.
Please try again.","error":"invalid_grant"}
Please check your username/password and try again

If attempting to upgrade using EWC GUI, a message similar to the following will be seen:

Last CCO Response
HTTP 400 Error: {"error_description":"
We didn't recognize the username or password you entered. 
Please try again.","error":"invalid_grant"} 
Please check your username/password and try again

Workaround/Solution


As a workaround, use another software upgrade method. Download the desired EWC-AP image, then load it into EWC-AP using TFTP, SFTP, or (Desktop) HTTP.

As a solution to this issue, upgrade to one of the following releases:

  • 17.9.5 or later
  • 17.12.3 or later
  • 17.14.1 or later

After the upgrade, the CCO method for upgrades will work.
