Looks like some.networking issues. Have you tried pulling directly without Proxmox, or maybe from a different source?

Yeah I had issues before when I tried to use the generic x86 install following the website instructions
Are you using Podman under the hood by chance? That would probably explain it if you're following docker instructions.
I can’t exactly solve your problem, but when I wanted to get HA running on proxmox I used these scripts
Completely painless and running in almost as little time as it took to download the files.
+1 to this. I grabbed the haOS VM proxmox script a year ago and it's been smooth sailing ever since.
It appears to be what I used. bash -c "$(wget -qLO - https://github.com/tteck/Proxmox/raw/main/vm/haos-vm.sh)"
Try following that guide https://community.home-assistant.io/t/installing-home-assistant-os-using-proxmox-8/201835
Try booting something different on proxmox like an ubuntu live desktop, just to make sure networking is working there. Seems like haos can't talk to the Internet.
Thank you, trying that now. I was able to ping 8.8.8.8, but idk if that's normal with these issues
