In this case, you may want to try the options below.

Inform Cloudkey to Adopt

set-inform http://ip.address.of.cloudkey:8080/inform

Where the ip.address.of.cloudkey is either a private address if it is local or the public address if it is remote.

returns:

Adoption request sent to 'http://ip.address.of.cloudkey:8080/inform'.  Use the Controller to complete the adopt process.

NOTE: Check if the Status line shows this is adopted.

If adopted then all done, otherwise try the rest of the statements below…

Reset AP and try to Re-Adopt

Disconnect the AP from the network. Wait about 5 minutes but no more than 10.
Log into the Controller on the Cloud Key and ensure that the AP is not present in any state. If it is then forget it, Devices → AP → Config → Manage Device → Forget.
Power up the AP but leave it disconnected from the network for now, wait until the AP LED is solid. Then press the reset button for just over 10 seconds, the AP will reboot and then come up as solid white.
Power down the AP and then connect it back into your network and power up. Do not attempt to adopt it yet.
Once it is powered up and has a solid white LED, ssh into it using the username ubnt and password ubnt and then issue the command:
```
upgrade https://dl.ui.com/unifi/firmware/U7PG2/4.3.21.11325/BZ.qca956x.v4.3.21.11325.200922.1139.bin
```
The AP will then upgrade and you should be able to adopt it.
Once it is adopted then you will need to enable the Uplink Connectivity Monitor on the Controller and allow the AP to mesh with other Unifi APs

NOTE: If that does not work then try plugging the AP into a different port of the switch, or trying a different switch or using a power adapter.
