AP2702i AP won't join 9800 vWLC - DLTS handshake error

Hello, I've setup an internal lab which uses the 9800 WLC (on AWS with a VPN to our lab). And now i'm trying to onboard an out of the box 2702i AP.

The join process fails: 

CAPWAP DTLS session closed for AP, cause: DTLS handshake error

* The AP is currently using DHCP 43 option to get the WLC details. are there any other options that needs to be sent (NTP?)

Did you ensure you generated a certificate for the AP's on the WLC?

Yes, I ran this command before adding the AP. Are there any debug commands which might be useful here?

I haven't logged in to the AP yet . Maybe there are some commands that needs to be executed on the AP before?

I did:

 

clear capwap ap all-config

 

That worked.

9800 required mandatory smart license for APs to register, might be an issue with licensing, what the smart license status (see image)
