There could be many reason, we’ll check one of them now.
As you need to start service again, it could be that app is killed because it ran out of memory.

To check that, let’s look at logs. Open system logs with text editor:

  • sudo nano /var/log/syslog

If you see OOM or Out of Memory entries for your app, it means that app got killed because it ran out of memory.
To fix it, you have 2 possibilities - Add Swap space or Upgrade your Droplet to bigger one.
If you want to go with Swap, How To Add Swap Space on Ubuntu 16.04 will help you.

If that’s not a problem, we can look at other logs but start with this and report results. :)
