Good afternoon, I'm trying to register a SLED11SP1 desktop with my ZCM11.2 Primary server, please see the below for the actual error message.

zac reg -g http://192.168.1.16 (have also tried with zac reg http://192.168.1.16)

Processing Command: reg




user name:administrator

password: **********
Unable to register with the server at: http://192.168.1.16.

Unknown or an internal error occurred.

Error processing the ZAC command


I have tried both the DNS record, and the IP address same results. Any ideas?
