Did you try manually creating the flash drive?

Yes, that has never worked for me on those flash drives sadly. I have done a full format on the larger flash, and now it says failed to load ldlinux.c32. I will try other flash drives to see if any boot.

Have not had my server for a week now.

Low and behold, tried on a different 4GB flash drive that I was given when I bought some school pictures of my kids and that boots first time, using rufus v 3.12 (I have also been testing different versions of rufus).

Replaced the pro key, and server is again up and running. I do wish we didn't have to use a USB key to start this thing though.
