There is a step missing in that guide. You need to edit this file -

sudo nano /etc/udev/rules.d/70-persistent-net.rules

and add a line for your networking interface. Usually if you perform sudo ifconfig -a you’ll find an ethernet interface names as ens4 or ens3p2 or something that like that. That needs to be renamed to eth1. Copy it’s HwAddr and add a line to the 70-persistent-net.rules in this format

SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="0a:83:3f:62:be:86", NAME="eth1"

Hi @maxymilianblack

If you run ifconfig -a which interfaces do you have? Please post text in code-tags instead of pictures.

Can you try to reboot the droplet? I have never seen this problem before on DigitalOcean, but I have seen it on some computers, where a full reboot fixed it. That was usually on machines that was upgraded from 14.04 to 16.04

Thank you @championswimmer. That’s exactly what my issue was after following this guide: https://www.digitalocean.com/community/tutorials/how-to-downgrade-digitalocean-droplets
