main server IP does not ping or ssh

[Maher Khalil]

After I reboot proxmox server, it stopped ssh and when I logged in using KVM, I was not able to ping google.
I checked resolv.conf and was not changed
I checked interfaces was not changed
all VMs can connect to internet without problem
The only problem is server main IP
any advice?

hi,

After I reboot proxmox server, it stopped ssh and when I logged in using KVM

is your server in a hosting environment?

I was not able to ping google.
I checked resolv.conf and was not changed
I checked interfaces was not changed
all VMs can connect to internet without problem
The only problem is server main IP
any advice?

can you ping an IP address like ping 1.1.1.1 from your PVE server? if that's working then you have an issue with DNS.

in any case could you post the outputs for the following commands on your server:
* pveversion -v
* cat /etc/resolv.conf
* cat /etc/network/interfaces
* ip a && ip r
