Failed to establish a new connection: [Errno 101] Network is unreachable

Getting “Failed to establish a new connection: [Errno 101] Network is unreachable” after the deployment when the machine is about to reboot. It would be great if anyone know the fix for this.

FYI

Hi,
I’ll assume it’s a VMware installation.
Did you check your NIC is connected to the right portgroup? Is addressing static or DHCP? Is VMware-Tools installed? What NIC driver are you using?
Cheers,
