Setup PXE in a Frankfurt location, I have PXE setup in other countries already

Problem: Hi so I am using Foreman, and I already have PXE setup in other locations but its not working in Frankfurt, how would I go about making sure it works there?
I keep getting this when booting…

Any help would be greatly appreciated.

Expected outcome:
I want to be able to PXE boot from Frankfurt
