Ubuntu Server Network Interface Error *Solved*

Morning All,

I woke up this morning to the beloved call of my colleague how updated our ESX Server that my netbox system wasnt reachable anymore.
Once i logged into the system i was greated with this error message

I thought it was a driver error with the original ens160 interface since its a vmnx3 so i added the ens33 interface with E1000.
No luck so far. Since I never had this error i could use some help.
Running on Ubuntu 20.04.1 LTS
Thanks :slight_smile: and have a nice and save day!

edit

I tried to bring the interfaces up with “ip link set ens33 up” and “ip link set ens160 up”. Did not change anything :confused:

The Solution was simple… Duplicate IP Adresses in the same network.
On ESX reboot a system started again that had the same ip address as the netbox system.
Once i shut it down everything is working again.
