Can't enable private networking on existing droplet
I've been trying to enable private networking on a Ubuntu 14.0.4 Droplet in SFO1 following the instructions here: https://www.digitalocean.com/community/tutorials/how-to-enable-digitalocean-private-networking-on-existing-droplets, but so far have had no luck. I'll power off the server and click enable under private networking, and the progress bar will come up, but after it finishes, it still just shows the button to enable private networking. If I power on the server, under private networking it says I have to power it off to enable private networking.
I checked under history and it lists "Enable Private Networking", but never "Cfg Reset."
Is there any step I'm missing here?
