iPXE hangs on boot during provisioning

I want to install Windows on a host. I’m using the default “Windows default iPXE” template.
The host succesfully switches to iPXE mode and it apparently managed to download the files from the proxy.
But the host hangs, with no errors, on the boot command at the end of the template.

Would anyone be able to help me with this ?
where can i find the logs?
