Advice For Windows 10 Hyper V

Need some assistance / advice regarding usage on Windows 10 HyperV. I was using trial version before where VirtualHere Server reside at HyperV Host and VirtualHere Client reside at Hyper V machine which reside inside the same PC as HyperV Host and it works brilliantly before this. Before this it can connect to the Server via Auto-Find Hubs. Without any chances being done, now it can no longer connect to the VirtualHere Server. Both option has been tried (Auto-Find Hubs and Specify Hubs) and failed.
My current network configuration:
I am using virtual internal switch that being used as Network Adapter for the HyperV Client. A wifi network adapter on HyperV Host is being shared with this virtual internal switch. On the HyperV Client, I have internet connection and success ping test to the IP of the wifi network on HyperV Host.

Appreciate any of support / assistance / advice on the issue currently I am having.

VirtualHere USB Server 4.2.4
VirtualHere Client 5.1.4

Sorry i dont debug network issues. VirtualHere uses TCP port 7575 so if thats blocked you need to open it
