E: Unable to locate package raspberrypi-kernel-headers

Hello there,
I tried to get the raspberry pi examples to work by going through the installation process all over again.
After I uninstalled drivers etc. I couldn’t install the hailo-all package.
The domain repository.hailo.ai could not be resolved, I checked for DNS issues but mine seems fine.
Is your repository for “hailo-all” for Raspbery Pi 5 offline?

What I tried:
sudo apt update
sudo apt full-upgrade

System Information:
Kernel Version : 6.12.25-v8-16k+
Debian GNU/Linux 12 (bookworm)

I read through all those community posts about the same issue not helping me, so I guess the service is down.

I’d be really glad if I could only know what’s the issue.

Thank you.
