## Symptoms

- Harmony Endpoint client fails to register with the Endpoint Management Server and the `cpdaApp.elg` log shows these entries:

```
[httpSenderImpl::sendRequest] url: https://<server_connection>:443/cp/connectionPoint/regep responseError: (null) statusCode: 200
[httpSenderImpl::sendRequest] request sent, response code:200
[CDAProtocol::handleResponse] ErrorResponse received to RegisterEndpoint request, error code= 72003
[CDAProtocol::handleResponse] ErrorResponse returned with unknown error code from server
```

## Cause

The **error code = 72003** returned by the Security Management Server indicates an authentication failure related to time-limited installation.   

As explained in the [Harmony Endpoint Administration Guide](https://sc1.checkpoint.com/documents/Infinity_Portal/WebAdminGuides/EN/Harmony-Endpoint-Admin-Guide/Topics-HEP/Time_Limited_Token_Registration.htm), time-limited installation is not supported on macOS.
