Unable to find my Proxmox server on my network?

[Flight6334]

I have a simple network, just the basic 192.168.1.0/24. I lost contact with the server few months ago (I'm not physically near it now) and I decided to restart my homelab. The PX server boot up as usual and now I'm unable on any address to find the web UI? The connection times out, I tried nmap, I got results for ports used by Proxmox, but when I ssh inside, It's one of my virtual machines hosted by Proxmox, not the system itself. It is almost black magic at this point.

I used to have an easy access with Traefik with a pretty URL but since then, my SSL certificate expired and I can't do anymore (I still have access to Traefik but for some reason, It doesn't incorporate m new SSL, anyway). So now, I'm doing with the old school IP.

Also, I could technically connect myself to the SSH but my dumb ass thought it was a good idea to remove password autentication. I didn't reinstall my laptop OS that I used to connect so I should technically still have the good privkey to log in, but in the meantime, I can't find this server.

As I'm really lost, if you have ideas I'm open.

Thanks!

Do you remember if your server host was in DHCP mode or fixed IP?

Some pointers that you can look into:
1- If you can access your router (typically 192.168.1.1 in your network), try to find the ProxMox IP address and Hostname there. Also take note of the MAC address if you can.
2- Once you find the ip address, open your web browser and access it with the port at the end (default is 8006). I.E > https://192.168.1.##:8006

No, I don't remember.

I searched in the router, and I have nothing. I feel like Proxmox doesn't have an IP address at all.

So nothing where anyone can help.
