Ubuntu VM lost connection in the middle of the night

I woke up this morning to find that at 3:30am this morning JetPack informed me that my website was unavailable. A few moments later I received an update from my 3rd-party monitoring that told me that SSH, HTTP, HTTPS were all unavailable on my host.

I had to resort to using my console to connect to my VM, which was running. Upon inspection I found that eth0 was missing on the VM. I ran dmesg and found that eth0 was being renamed to ens4. I changed my interfaces lines from eth0 to ens4 and restarted networking. ens4 now gets the ip address I expect, but I have no network connectivity. I cannot even ping the gateway, it says host unreachable.

I need some advice here, I’m not getting very helpful answers from DO Support other than to check files which all look normal to me.

All I have to go on is at 3:30am or so there is a log of my Droplet powering on - I wasn’t awake at 3:30am. I don’t know who or what authorized a power on of the VM, but what I do know is that I am with a VM with 2 websites that is down.


Update: I changed eth0 from ens4 which apparently was incorrect. I have changed it to ens3. I then restarted networking.

I can now ping the gateway, but that’s about it…

Andddddd I rebooted after changing the /etc/networking/interfaces from eth0->ens4->ens3 and now my droplet is working.
