Problem with Hassos install on Hyper-V

Hello,
I am installing Hassos on Hyper-V.
The installation is stuck on the " Preparing Home Assistant" stage.
If I run “core check” on the console, it returns an unexpected server response error.
ha dead I created the virtual machine from https://github.com/home-assistant/operating-system/releases/download/4.14/hassos_ova-4.14.vhdx.gz
