restarted by droplet last night using CLI. Didn’t pay much attention, because i’ve never had too.
Today realized I hadn’t received any emails, which is that server. Couldn’t load zpanel via web browser. Finally got in it through console. Restarted again and saw an error on startup saying NetworkManager-wait-online had failed.
Powered off via shutdown command. Then started again. same failure.
ifconfig eth0 shows NO ip.
through console, journalctl -xe is almost useless because it cuts off text.
stopped network via init.d, flushed dev via ip command, started networking again. nothing.
EXCEPT NetworkManager-wait-online is now running, before the flush systemctl status said it wasn’t… but networking still won’t start.
also: my registered email address for DO is on that server. So i won’t get notifications of replies until i refresh this page. I’ll try to keep watching.

I’m not sure it’s resolved… however, i finally checked the ifcfg-eth0 script and saw it was to dhcp. the IP wasn’t in there, nor gateway, mask, dns, etc. So I manually added it even though a warning at the top of the file said not to edit, it was created on boot up by cloud something.
I made it look like the format of my other droplets, saved, and restarted network.service, bam I have internet.
Is this a centos issue after an update or did DO have an issue?
Doing a little research into this issue, it seems that CentOS 7 Droplets that are upgraded to CentOS 7.4 and cloud-init 0.7.9 can experience an issue where the Gateway is not properly set by cloud-init on boot. This also seems to be solved in our newer CentOS 7.4 Droplet image.
A bug report with information related to this issue with cloud-init can be found here:
so after putting all the IP information back in, I can’t reboot, otherwise I have to do enter it all in again.
I found this fix but it looks like we have to wait until it actually gets implemented upstream… @Surety01 I think this comment may be a temporary fix.
EDIT: I just applied the cloud.cfg edit/fix to my CentOS 7.4 droplet, and came back to confirm that it works, as I applied it and rebooted to test as well - so far so good.
