The connection to the Windows Sandbox environment was lost.

An existing connection was forcibly closed by the remote host. (0x80072746)

Answer 1

Hello

Thank you for posting in Q&A forum.

It can be caused by several issues. Here are some steps you can take to troubleshoot:

1. Ensure that Windows Sandbox and all related features (such as Virtual Machine Platform and Hyper-V) are enabled.
2. Restart Required Services:

Restart the necessary services for Windows Sandbox. Open the Services application and restart the following services:

Network Virtualization Service

Virtual Disk

Hyper-V Host Compute Service

Container Manager Service

3. Check your network connectivity.
4. Check the Event Viewer for any related error logs that might provide more details about why the connection is being closed. Look under Windows Logs > System and Windows Logs > Application.

I hope the information above is helpful.

If you have any questions or concerns, please feel free to let us know.

Best Regards,
