So I double checked the urls for pulling down the vmlinuz and initrd.img and they are fine.

Listed here (public urls):
https://storage.cloud.google.com/public-...-1/vmlinuz
https://storage.cloud.google.com/public-...initrd.img

They are the same CentOS images as the working script just downloaded and hosted somewhere else (gcloud).
When I download them manually, they are 6 MB and 50 MB respectively just like the centos.org files so I think they are exactly the same.

However, imgstat returns something interesting.

In the working script:
vmlinuz: 6639904 bytes [bzImage] [SELECTED] ...
initrd.img : 52584760 bytes ...

Just as expected.

But in the non-working script:

initrd.img: 74115 bytes [PXE-NBP]
vmlinuz: 74093 bytes [PXE-NBP] [SELECTED]

These sizes (70kb) are way off and very similar so maybe an error response. The data type also seems not be bzImage and instead PXE-NBP. So far, looks like it is not able to download these correctly. Given that I can download those files from the given urls manually and they are at the expected size it seems to be an error in how I'm pulling the kernel and initrd down. Anything special I can do to debug this step? HTTPS is an enabled protocol (in the features list when iPXE starts) but it could be some issue with that.
