Virtual Here Through VPN Not working

I Would like to use virtual here through my won VPN.

I love your software, we are using it successfully in our office but when I go home and use VPN to access my office resources (files/ shared drive ) I cannot find the USB server. 

I tried specifying the IP address through the settings ( specify server button ) but it keeps looking for the server yet nothing is found. 

It works through your easy find address but that is not how we operate.

Could you please describe why I can see other resources ( printer, cloud, etc. ) in our LAN through VPN but not the Virtual Here server?

The Virtual Here server is installed on a Synology NAS, purchased license and works flawlessly in LAN.

VPN I use is OpenVPN with access in LAN. Even modified windows hosts file to specify the name of the VPN server to pint to that specific address. nothing yet

 this is the system message log:
