The VM clients can communicate with the ePO server. But when you run the command mvadm status on the client, the following is displayed:
 

Primary Server:	NONE:9053 [Not Configured]
Secondary Server:	NONE:9053 [Not Configured]
SVA Manager:	XXXX.XXXX.XXXX.XXXX:8080 [Connecting]
Protection Status:	Disabled

When you perform a Telnet to the OSS on port 9053 (default port) fails, it even though it is possible to ping the OSS and SVA Manager. The above is seen when ePO administrators have changed the Offload Scan Server 4.x.x policy option Scan Server port and SVA Manager (default 8080) port.
