On Apex One Server, navigate to the file C:\Program Files (x86)\Trend Micro\Apex One\PCCSRV/Private/ofcDdaSvr.ini
Check the value of OfcDddaServerRegistered if it’s 0, meaning unregistered status.

On the same file in step 1, make sure the APIKey matches the one on the DDAN Console.
If it’s different you can stop the Apex One Deep Discovery Service, modify the APIKey value on ofcDdaSvr.ini and Start the service again to re-register.
Make sure that Apex one can communicate with DDAN on port 443(Default).
Perform test connection from Apex One to DDAN.(Via PowerShell) or via Telnet Test-NetConnection -ComputerName DDANIP -Port 443
Restart Apex One Deep Discovery Service to initiate re-registration and check the values of the below keys for indication:
- OfcDddaServerRegistered
- ResponseCode
If the issue persists, kindly collect CDT logs from Apex One Server while restarting Apex One Deep Discovery Service for further troubleshooting and diagnostics.
An Example of successful registration will look like the one below.
