[SOLVED] Can't Access Web Gui Only SSH

fvp1992 · Mar 14, 2024

I was getting hostname error 5000 when attempting to access my proxmox VMs so I restarted the node and now I cannot access any of it through the Web UI. I can SSH to it but I am lost on what to do to resolve. I think I messed up changing hostnames as I recently got a new router.

Any help would be appreciated. I do not want to have to start over

If you manage to SSH in, then you know the IP_ADDRESS of your PVE.

What happens if you go to https://IP_ADDRESS:8006/

Nothing happens, it times out.

I've been accessing it at this same IP address for years and used this IP to ssh to it.

Also when checking in my router leases it is not showing up as grabbing a new DHCP address.

I understand that presently you can SSH into it from a different machine. Is this the same machine that you're unable to connect to the Web UI?

Also show me the IP address (local) of the machine you're using to access PVE via SSH, and the command you're using to connect, which should include the IP address (local) of the PVE.

Also what is your router's Gateway.

Also what is the output of cat /etc/network/interfaces on the PVE. And the output of ip a and then also ip r please.

You should be using a Static address for your PVE. Preferably out of the DHCP range.

Your reply is still incomplete (re-read my post for requested info).

However I notice that the machine you're using to try to connect from is on Wifi. Can you try and find a machine that is on the same wired Lan network as the PVE. (You may have a different network for Wifi in OPNsense).

Same results when attempting to access the Web UI from a wired LAN device.

Did you check if all services are running?

Have you checked if the specific file/key exists?

bbgeek17 · Mar 14, 2024

It seems like you changed your hostname but perhaps not fully. Your shell shows that the host may be called "ProxMox", yet /etc/hosts contains "pve-cryo"
This can easily trip up multiple services, including PVE.

Go through the steps here https://pve.proxmox.com/wiki/Renaming_a_PVE_node and check all the relevant places.

Also, check available space on your root disk: df -h

Ok this is the messed: As you see here your hostname is ProxMox (according to /etc/hostname)
BUT according to /etc/hosts its called "pve-cryo"

Thank you so much, saved me countless hours.

I updated /etc/hosts and am now able to see everything running. Time to do backups and more research before I resume any more tinkering.
