VM got IPs but not my Proxmox anymore

[Haspirean]

Hello everybody,

I'm David, 28yo from France. I start IT science since 4 years now. I'm so glad to discover Proxmox and their community.
I install a proxmox server in a old PC, since the begening all working good, i can access to it via Https and and i also reserve an IP on my DHCP router from my ISP.

But for my vacation i stop my pc for 2 weeks. now i start it again and i can't find the IP of my proxmox server on my ISP router dhcp lease.

What's it strange is that i have 3 VM working on it and all of three get an IP and i can acess to it but not my Proxmox.

Do you know what can be the problem?

thank you all.

what is the output of 'ip a' ?
normally pve is not configured with dhcp but with a static ip
(in the installer we still use dhcp to suggest an ip)
