           - Check if you have sufficient (ap-) licenses with show license summary , also check if the regulatory domain of the ap and controller match.

Did you convert this AP to Mobility express as well? You should not have two controllers.  You will have to choose one ME WLC and another as Save AP, this slave AP should be lightweight.

To remove ME on Slave AP you can try the below command

config ap unifiedmode {WLC Name} {AP Manager IP}

The AP log you attached is not the full log - we need to see the full log from power on.

Have you tried a factory reset on that AP?

[GuillermoCuruchaga13837]

Hello, I factory reset at the AP, the problem resolve.
