[SOLVED] Loss of internet, service networking restart

[roch]

Hi
I am incountering a weird behavior
My VM is set to bridged
When it's running I loose internet connectivity on the proxmox server, until I manually run
service networking restart
But then I loose access to the VM network

When it is not working on proxmox, I can ping the local network but nothing outside the NAT

It's always useful to show us your host network (cat /etc/network/interfaces) config and guest network config.

I was about to put them

cat /etc/network/interfaces
auto lo
iface lo inet loopback

iface enp1s0 inet manual

auto vmbr0
iface vmbr0 inet static
        address 192.168.1.50/24
        gateway 192.168.1.254

        bridge-stp off
        bridge-fd 0

on the guest I dont have /etc/network/interface, its homeassistant

ip a

    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00

You actually solved it without knowing

Thank you

For reference, I installed a desktop on the proxmox server directly, LXDE, which comes with connman
apt purge connman solved it for me too
