USB client stopped connecting after upgrade to Windows 25H2

Submitted by ksykes on #1

I had been using VirtualHere without issue for about a month, with the server running on my physical machine and the client running inside a VM on the same machine. After upgrading the VM to Windows 25H2, the client is no longer able to attach to the server:

  • The server is running and appears to have found all of the devices based on the server logs
  • The client periodically tries to connect to the server with the correct IP, but is not able to connect

Thoughts? Is there any info you need to help diagnose this?

Sounds like it might be a firewall issue. Can you let TCP 7575 through the firewall on the client.  Can you ping the ip address of the server?

I am able to ping the IP address and added an inbound and outbound rule for port 7575 on the client. Neither helped. I also tried uninstalling the client service and restarting as admin. So far nothing has worked.

Open cmd.exe then type

telnet <ip address of vh server> 7575

It should connect and show some characters on the screen. If that doesnt work you still have a firewall somewhere blocking it.

thanks - telnet shows there is still something blocking the port, i'll look into that more.  (telnet on the server side worked fine)

The problem was on the host side, not the client side. Somehow the firewall did not allow VirtualHere on the private network. Checking that box fixed the issue.
