Proxmox web ui not reachable after unplug

Hey, I know there's a lot of threads on this, but can't find anything to help me fix it. I have a new proxmox instance installed on my old pc for around a week, everything was fine, just playing around with some lxc's and networking stuff, like setting up some cloudflare tunnels, just testing some scenarios, did multiple reboots over the last week, this weekend the pc was shut down, starting without any issue afterwards. Yesterday I had to completely unplug it, had to take out my GPU for some mods, and now after reinstalling it and booting back up, I can't reach the web UI anymore...

Thought this would be some networking stuff, since I didn't have the ip reserved, but I can't figure it out, everything looks perfect...

So I have access to the server manually, and I tried:
ip a -> shows the same address, the old one, 198.162.1.136/24
ping google.com -> works fine
ping 8.8.8.8 -> works fine
added 198.162.1.136 as a reserved address in my router, even tho I also checked connected devices and the server was already showing with this address assigned...but still nothing
ip route list -> default via 192.168.1.1 dev vmbr0 proto kernel onlink \ 192.168.1.0/24 dev vmbr0 proto kernel scope link src 192.168.1.136

don't know what else to try...only thing weird are these errors in journalctl, that I can't really find much on:WhatsApp Image 2026-03-31 at 13.59.51.jpeg

Sorry in advance if this is wrongly placed or redundant, I'm new here! XD
 
Hi @Andrei18 , welcome to the forum.

Have you played with clustering this system at any point? The screenshot indicates that not all PVE services are starting. You can check "systemctl" for additional information. Also, "journalctl -b0" may be informative.
You mentioned that pings work, are you able to SSH into this server? If you are, providing information in Text format encoded with CODE tags would be more helpful than screenshots.

Cheers

hey man, thanks for taking the time to reply!

I don't think I have, it's just a fresh instance, I have only an LXC with cloudflared, an LXC with an uptime kuma, and a small ubuntu server VM.

I managed to ssh into it now, this is the output of journalctl -b0:

Hi. The output you provided is from the very first moments of your PC boot. It contains nothing of value for the question at hand.

I've asked AI to generate a quick list of commands that can assist in troubleshooting a failed PVE instance. Please run them, examine them first on your own. If you do not find anything that helps, post the data here.

Do use CODE tags when pasting text. You can find them in the menu of the reply Text box. The icon is </>.
If the output is long, you can use SPOILER tag, or attach a file.

Good luck

Code:
pveversion -v
uname -a

systemctl list-units --failed
systemctl status pve-cluster
systemctl status corosync
systemctl status pvedaemon
systemctl status pveproxy
systemctl status pvestatd

journalctl -u pve-cluster -b
journalctl -u corosync -b
