Troubleshooting "Cannot Connect to the Virtual Machine" error in Hyper-V

I'm running Windows 11 Pro (Client) version 23H2 on a host machine and I'm having trouble connecting to a guest OS machine created using Hyper-V. I have already tried creating multiple guest machines, but I keep getting the same error message, "Cannot Connect to the Virtual Machine." Although I can see an image of the machine booted up in the Hyper-V Manager window, I'm still unable to connect to it. The host and guest machines are both running on the same PC. Can someone suggest a solution to this issue? I have enabled virtualization in the BIOS, updated Windows, and tried starting and stopping the service and restarting my PC. I have also created both internal and external switches in the Virtual Switch Manager. Here is a screenshot of the error in Hyper-V Manager.

    Hi Adriane,

    Hope you're doing well.

    1. Sometimes, third-party antivirus software can interfere with Hyper-V. Consider temporarily disabling any antivirus software to see if that allows you to connect to the guest OS.
    2. Ensure that the network adapter is correctly configured and attached to the virtual switch you've created. Also, verify that the correct network adapter is selected in the Hyper-V settings for the guest OS.
    3. The Windows Firewall might be blocking the connection. Try adjusting the firewall settings to allow Hyper-V connections or temporarily disable the firewall to test the connection.
    4. Verify that all necessary Hyper-V services are running on the host machine. You can check this by running "services.msc" and looking for Hyper-V services.
    5. Ensure there is proper communication between the host and guest OS. This includes checking the network settings and ensuring that both are on the same network or subnet if necessary.
    6. Ensure that the Hyper-V has the necessary permissions to access the VM configuration files. This can sometimes be an issue if the files are stored in a location with restricted permissions.

    Best Regards,
