Private Networking Not Working

Networking Ubuntu 16.04

So I got private networking. MY server was already made and in use and I decided to enable private networking on my servers. They do not communicate together.

I followed the guides, adding this to /etc/network/interfaces
auto eth1
iface eth1 inet static
address Other servers ip

Did extensive testing between my servers. But had no luck at all, they don't ping via the private ips, only public ips, and that are infact in the same datacenter

Now things are just getting worse.

As now the interface isn't showing up, if I forcefully start it with ifconfig, no network information shows up. Basically It's worse than before following guides.

I have waited for 48 hours for Digital ocean to respond after they told me what to try and they still have not responded...very very poor customer support. Does the community have any answers?

PS. It's all on Ubuntu 16.04-17.04

Same problem here. There is no eth1 interface listed by ifconfig
I am using Ubuntu LTS.

same problem here, have 3 droplets, one of them dont ping anymore

@jvmmdev Did you ever figure out what it is?

Hey guys.

For all that was wondering. I never resolved this. I got sick of waiting for Digital ocean to respond to my ticket once a day...if that. I waited 3 days for them to respond. To which is was never resolved.

So I just destroyed my droplets and re-install 2 with private networking simultaneously.

Problem fixed.

Yes, adding private network on prior created instances not working, we have tried several ways to make the private networking work with initially crated instances, nothing work,

only possible solution is to destroy and create again.

I had the same issue and nothing helped. I decided to enable ipv6 and that, somehow, made eth1 start showing up when I run ifconfig -a.
