Original GitHub issue: https://github.com/netbootxyz/netboot.xyz/issues/1260

Describe the bug

CentOS Stream 8, 9 and Fedora 38 appear to fail while retrieving vmlinuz and initrd files. Possible more RHEL distributions are affected, I did not test exhaustively. I am able to install other distributions and I was able to install CentOS Stream 8 a couple days ago on the same system. I have tested across several systems now at 2 different locations.

To Reproduce
Steps to reproduce the behavior:

Attempt to install CentOS Stream using netboot.xyz.iso.

Expected behavior

vmlinuz and initrd files should load and installation should proceed as usual.

Screenshots

It appears that mirror.stream.centos.org is using TLS 1.3 and iPXE does not at this time support it. It was working at one point so I suspect they dropped TLS 1.2 on Cloudfront. I also noticed that they still list http in their list of mirrors, but it automatically does a redirect to https now too.

https://mirrors.centos.org/mirrorlist?path=/9-stream/BaseOS/x86_64

curl http://mirror.stream.centos.org/9-stream/BaseOS/x86_64/

<hr><center>CloudFront</center>

</html>

I'll have to switch mirrors to get it to work. Fedora 38 seemed to work for me tho.

I reached out to a contact at Red Hat to see if they see if they could dig into it.

Updating the mirror for now, will continue to monitor if we can get it fixed to work with us upstream.
