Client can't find server

Suddenly the client in one of my virtual machines can't find the server. I have made sure Windows is updated and I have tried downloading both the server and the client again. Also made sure to add exceptions to windows firewall.

The Virtualhere client windows is almost empty, and just shows "USB Hubs" but nothing else.

Any idea to how I can solve this? How can I make it work again?

Using Windows 10 pro 64bit and Hyper-V as virtual machine (client).

I tried deleting the vhui.ini file (backed it up first). It made no difference so I replaced it with the backed up one again.

Try uninstalling bonjour from the client machine and let the virtualhere client install bonjour again
