Other relevant data:
proxy server has dhcp pointing next-server to the foreman box, is that correct? (this was the only way it booted into grub menu ) shows downloading NBP - and success goes into menu. after pressing enter to discovery image , black screen no cursor blinking either.

BIOS or UEFI?

What is your PXE configuration file that is actually acquired, can you paste it?

Can you record a screen and publish it somewhere? I haven’t seen that yet.

i can say its closed, the far foreman box was toooooo far for tftp dl. so bright the next server (proxy) to be the tftp locally. all good now
