Cubase IC Pro no longer working with Windows 10 Pro after iOS 11.3.1 Update

Having no luck running Cubase IC pro on my iPad pro 10.5 with Windows. Ever since the recent iOS update (ver. 11.3.1) I can longer get the application to connect to Cubase Pro 9.5.

In the past, I have used Cubase IC pro during countless recording sessions with the Windows version of Cubase 9.5 Pro. On my Apple Tablet, I now get the message: “The operation couldn’t be completed. Network is down”

My setup includes Windows 10 Professional, Asus Zephyrus Laptop,
I am familiar setting up an ad-hoc network on Windows 10 Pro. I have tested 2 wireless network cards that support hosted network and I can’t get either them to work now.

Is there anyone else experiencing the same problem?
