have a problem with my proxmox server

[jcss21]

Hi guys i need some help with my proxmox server

after i did a update on my proxmox server i can't reach the proxmox gui anymore
but the strange thing is i can reach all the vms on the proxmox server that are running


thank you in advanced for the help

Best guess: Network Interface name (enpXsY) has changed and you need to adjust it in file /etc/network/interfaces.

You need console access to the Proxmox host, then show the content of file /etc/network/interfaces, as well as the output of command ip a s.

i have check that and the names are the same or am i over looking something

„Image Not Found“ is all I see. Did you use this button?

How could we know what you have configured - your posts contain zero information - that's why @maxim.webster just gave a "guess"...


Please start by giving us some information, like the copy-n-pasted output of some commands, run on a PVE host (either via SSH or via "Datacenter --> <one Node> --> Shell", both ways allow copy-n-paste):

PVE System information:

• pveversion -v
• head -n -0 /etc/apt/sources.list /etc/apt/sources.list.d/* # all repositories
• apt update && apt -d -y full-upgrade # update package list and download (not:install) packages

Basic network information:

• ip address show # currently active IP addresses on one NODE
• ip route show # currently active routing table on one NODE
• cat /etc/network/interfaces # configuration of the network and/or ifquery -a for comparison from one NODE
• cat /etc/resolv.conf # DNS resolver settings
• ping -c 1 -W 1 9.9.9.9 # a simple "ping" to verify outgoing routing
• host quad9.net # a simple DNS lookup to verify reachable DNS servers

Those are examples. You may add/edit commands and options if you can enrich the information given. Oh, and please put each command in a separate [CODE]...[/CODE]-block for better readability.

"bridge-ports servers" makes no sense. Please compare: https://pve.proxmox.com/wiki/Network_Configuration#_default_configuration_using_a_bridge

Actually, it looks valid as vmbr0 is a bridge on the network interface „servers“, which by itself is a Tages vlan interface for the „raw“ device enp10s0f0

Not really straight forward, yet valid.

Quest remains: Which of the many interfaces is actually physically connected?

Can you show output for the following:

cat /etc/hostname

cat /etc/hosts

2 things I notice (you've blocked out the actual name addresses - so I'll ignore them):

1. Your hostname is named PX1, but you have px1 in the hosts file. I believe this is case-sensitive. So change that last word in that hosts file on the line from px1 to PX1

2. You have a third entry with a different IP address on the third line. IDK why, so maybe comment out that line by placing a # (ampersand) sign at the beginning of it.

Good luck.

i comment the 3th line out and edit the hosts like you pointed out but no luck

but no luck

i have fixed it i disabled al the network card and edited it all one buy one it seams the problem was that it got stuck when getting a ip address in the wrong Vlan segment
