WorkBench Failed to Open and Connect to AKD

Trying to connect WorkBench v1.16.0.41 running on a virtual machine with IP address 172.27.1.213 and subnet mask 255.255.0.0 to my AKD-P00606-NBEI drive with IP address 172.27.2.60 and subnet mask 255.255.0.0.  WorkBench has found the devices, but never completes the connection.  When I check "Specify Address" I get the same result.  and same result when trying to connect direct to the drive via simple unmanaged switch.  The AKD scrolls the correct IP address and runs fine.

Ping works fine, with 1ms reply.  tracert shows a direct connection.  arp -a shows the correct MAC. 

The About page on WorkBench shows the correct system IP, but also shows IP 127.0.0.1.

Reboot the AKD drive by cycling the 24V power, and close and reopen Workbench.  Then try to connect.  If Workbench is connected to an AKD drive and the drive is rebooted without first disconnecting Workbench, then it will not reconnect.  The drive must be rebooted while Workbench is either closed or disconnected.

If it still won't connect, try a direct connection from the PC to the AKD.  Set both rotary switches to zero.  Configure your PC for DHCP mode.  Clear out the IP address by pressing and holding the B1 button for about 30 seconds.  Then try connecting.  If it connects, you can set the IP address back to what you were using.
