New HA VM Install, Unable to Update

I just setup Home Assistant with the Hyper-V VM on a Windows 10 Pro machine. I now receive this error when trying to update HA:

“Error updating Home Assistant Operating System: ‘OSManager.update’ blocked from execution, no supervisor internet connection.”

Any ideas for how to deal with this?

Thank you

The Hyper-V default switch is in internal mode and automatically uses NAT, and the default switch cannot be modified.
You might create a new external vSwitch and connect the guest (HAOS VM) to the new external switch.
