Networking not working after droplet resize

Hello Everyone, I resized my droplet yesterday and the process went through without any errors or warnings. When I powered on, I discovered that my networking had stopped working. I’m able to access it through the web console but not able to ping my IP from outside and ping from within the droplet doesn’t work. It shows: “Network is unreachable” I’m not even able to ping the gateway.

I checked my routing table and it looks empty. When I try to add a routing rule it says “Error: Nexthop has invalid gateway”

Here’s my /etc/network/interfaces :

Anybody tell me what I’m missing or doing wrong?

So I managed to fix the issue. Turns out my both interfaces eth0 and eth1 are going down after a reboot. I have to run the following after that:

ip link set eth0 up ip link set eth1 up ip addr flush dev eth0 ip addr add X.X.X.X/20 dev eth0 route add default gw Y.Y.Y.Y eth0

X.X.X.X is your droplet’s IP and Y.Y.Y.Y is your gateway

These settings vanish after a reboot. Anyone who know why?

@alexgeorgiev Thank you so much for your help :)


Twice now I’ve seen this happen and both times my fix has been to (re)install the cloud-init and cloud-guest-utils packages.

Hi everyone, I have the same problem after resizing my droplet. Do some has a solution for this?
