Netwoker Client Direct Backup not Working

Hi,

We have the NW 9.1 deployed on a VM. OS is Win 2012 R2. We are expecting backup slowness on our DB client. It contains ~1.4 TB data. We are use the client direct for backup the data to DD. To investigate this issue we have rendered the daemon.raw file in the NW server and go through it. Then we are able to identified client direct backup it not happening. Pls refer the below log output.

Then we have check the connectivity between the client and DD vice versa. Connectivity is fine. And we are use the dedicated VLAN for the backup purpose. That means all the backup clients and DD are in the same range.

How can we solve this issue. Pls advised.
