[SOLVED] WebUI not available after reboot

[szeoguprer]

I've setup Proxmox yesterday, changed the repository to pve-no-subscription and installed updates.

Today I did the following changes:

• Changed the IP and Gateway of vmbr0 via GUI because I wanted to move the server from the secure network to a DMZ.
• Changed the hostname in /etc/hostname and /etc/hosts.

And then I rebooted the machine.

There is only the login prompt but not the "Proxmox is available under https://xx.xx.xx.xx:8006/" message.
I can't access the web interface anymore.

But I can connect to the server via SSH.

Where's the problem? What did I wrong?

From the Proxmox host I'm able to ping the gateway 10.2.0.1 but I don't have connection the the internet.

Here is my /etc/network/interfaces:

auto lo
iface lo inet loopback

iface eno1 inet manual

iface eno2 inet manual

iface eno3 inet manual

iface eno4 inet manual

auto vmbr0
iface vmbr0 inet static
        address 10.2.0.2/24
        gateway 10.2.0.1
        bridge-ports eno1
        bridge-stp off
        bridge-fd 0

This might also be useful information...

root@pve:~# systemctl --failed

Okay, I've found the error myself.

This line in my /etc/hosts was:
10.2.0.2 pve.sub.domain.tld proxmox but it should be:
10.2.0.2 pve.sub.domain.tld pve

I did only change the first appearance of the hostname, but not both.
Whoopsie...
