No route to host (595) for VMs and LXCs

[johannes-z]

Hello! I had a problem today where I couldn't get past 'loading initial ramdisk`. I restored grub and the ramdisk from recovery, and was then able to boot into proxmox again. However, the web gui didn't work, so I read that it's because of a wrong /etc/hosts entry. I *fixed* that, and the gui came back up after a reboot.

But now none of my VMs and LXCs are accessible. Clicking on them in the gui shows "No route to host (595)". I'd like to bring them back to life, but if there isn't anyway, can I atleast somehow save the data?



This is my current config

# $> cat /etc/network/interfaces

auto lo
iface lo inet loopback

iface enp3s0 inet manual

auto vmbr0
iface vmbr0 inet static
        address 192.168.1.4/24
        gateway 192.168.1.1
        bridge-ports enp3s0
        bridge-stp off
        bridge-fd 0

# $> cat /etc/hosts

127.0.0.1 localhost
192.168.1.4 homeserver.home.local homeserver

# The following lines are desirable for IPv6 capable hosts

::1     ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters

I found the issue I renamed the host from home to homeserver, so all guests lost their connection to the host.It works now
