Cisco AP disjoined from EWC

[Torken]

Dear community,

This is my first post. English is not my mother tongue, please don't be harsh.

I received some new Cisco 9115ax aps. So, I want to configure an embedded wireless controller because I have 7 aps.

I followed this cisco guide : https://www.cisco.com/c/en/us/support/docs/wireless/embedded-wireless-controller-on-catalyst-access-points/215303-embedded-wireless-controller-conversion.html

The problem is, when I am configuring IP address, I got this log message (I changed my mac address to 0):

*Oct 31 02:34:47.535: %CAPWAPAC_SMGR_TRACE_MESSAGE-5-AP_JOIN_DISJOIN: Chassis 1 R0/0: wncd: AP Event: AP Name: AP0000.0000.0000, MAC: 0000.0000.0000 Disjoined
*Oct 31 02:34:47.898: %CAPWAP_IMGDWNLD_TRACE_MESSAGE-5-CAPWAPIMGDWNLD_EWC_AP_AP_LIST_EVENTS: Chassis 1 R0/0: wncd: List Event: AP with wtp_mac ac4a.56e4.bea0 for Image Type a                                                               p1g7 is removed from Master AP list
*Oct 31 02:34:47.907: %PEER_SELECTION-5-EWC_PEER_SELECTION_EVENT: Chassis 1 R0/0: wncd: HA Event: Internal AP 'AP0000.0000.0000' disjoined. Standby selection is now DISABLED

On top of that, after giving an IP address, the AP led is blinking green and red (before ip address command the led is holding green)

It is been at least 3 week I am working on this issue but today I am out.

Please if you can help me, I will be really relieved.

Components used :

 - C9800-AP-iosxe-wlc (controller image)

 - ap1g7 (ap image)

Thank you

You should start from scratch and only work on one of the ap's.  There are videos that can also help, just search for "Cisco 9100 EWC" in youtube.  Also take a look at a few blogs like this: https://howiwifi.com/2020/03/19/from-shelf-to-survey-cisco-9100ax-ewc-conversion/

I typically do not use the day 0 and cancel that out to configure the EWC from the cli, It's also a good idea to factory reset the ap by holding the mode button for 20 seconds or when the led flashes red.
