@sebastian-roth Ok - thank you - that works! ( I actually did see mention of this but did not quite follow through on testing it)
ipxe boot issues with https enabled (I enabled https on the old server and it all went wrong).
Ran into this issue again with new server this morning – looked at the system time of the pc, date was way off – corrected and booted fine…I gather system time + UEFI + https ipxe is crucial?
Regardless, I appreciate the quick replies!
