The following lines in your /etc/network/interfaces have a typo:

              bridg_ports eno1
              bridg_stp off
              bridg_fd 0

It should be bridge_ and not bridg_

Another typo that is present throughout is
iface ino1 inet manual

ino1 should most likely be eno1, the same for 2 to 4

typing mistakes ! ortograph corrections doesnt help at all ! since i had to write it down from my laptop , its not a copy past
and i think it would be an other errors if it was so

Well, trying to debug something with typos does not really help
Can you access the remote console on the iLO of your server?
What is the output of ip a? Do you see the vmbr0 interface with the assigned IP address?

Hey apologies for the hijack but I have the exact same issue. I can raise a new thread if needed or preferred.

I've got a fresh install of 6.1 onto Dell R410 II and I have the following issues straight out the box:

• No GUI at boot / or after reboot
• Cant ping the PVE host

Things I've tried / helpful info:

• I've reinstalled twice, with the same results above each time.
• ran apt update && apt dist-upgrade && apt upgrade it's broken before and after running this
• Curling the GUI from the PVEHost shows that the GUI is running!

  curl k -s -k https://localhost:8006 | grep title
  <title>R410-02 - Proxmox Virtual Enviroment</title>

• "pve-firewall status" by default returns "Status: disabled/running" I've stopped it so it returns "Status: disabled/stopped"
• /var/log/pveproxy/access.log only contains my local curl requests and nothing else
• There is nothing in IP tables
• /var/log/pve-firewall.log only shows where I stopped or started it
• ip a shows the eno1 state as up and using vmbr0, vmro0 also appears to be configured with valid IP and sub net
• tried stopping / restarting networking via /etc/init.d/networking stop / start

so, I just figured it out... in reply to my own problem above and hopefully others too:

/etc/networking/interfaces the vmbr0 doesn't have any dns-nameservers defined.
I added in googles 8.8.8.8 and restarted network services with:

 /etc/init.d/networking restart

and everything started working.

/etc/networking/interfaces Before:

auto lo
iface lo inet loopback

iface eno1 inet manual

auto vmbr0
iface vmbr0 inet static
    address x.x.x.x
    netmask x.x.x.x
    gateway x.x.x.x
    bridge_ports eno1
    bridge_stp off
    bridge_fd 0

iface eno2 inet manual
....

/etc/networking/interfaces After:

auto lo
iface lo inet loopback

iface eno1 inet manual

auto vmbr0
iface vmbr0 inet static
    address x.x.x.x
    netmask x.x.x.x
    dns-nameservers x.x.x.x
    gateway x.x.x.x
    bridge_ports eno1
    bridge_stp off
    bridge_fd 0

iface eno2 inet manual
....

if you wish to define multiple name servers, they are just space delimited, not comma.
