You've just configured an Ubuntu server and encountered network issues. The connection initially worked after changing the interface settings, but it resets on reboot. Try setting a persistent network interface using `netplan` or `ip` configuration to ensure it stays active across reboots.
Update the specified file in /etc/netplan and run the commands to apply changes. Follow a guide for NetPlan setup on Ubuntu 18.x+.
