Zigbee2mqtt not working anymore after reboot. Also, no logs are created.

When I check the status:
osmc@osmc:~$ systemctl status zigbee2mqtt.service

• zigbee2mqtt.service - zigbee2mqtt
  Loaded: loaded (/etc/systemd/system/zigbee2mqtt.service; enabled; vendor pres
  Active: active (running) since Fri 2018-12-07 23:13:28 CET; 4s ago

  CGroup: /system.slice/zigbee2mqtt.service
  `-1720 npm

Dec 07 23:13:28 osmc systemd[1]: Started zigbee2mqtt.

No logs are created. It keeps creating empty folders. Also, the light on the USB sniffer turns off.

What can I do? Tried this: #28

I upgraded node.js a few days ago and it kept working after reboot

[CypherMK]

I get this info:

osmc@osmc:~$ node -v
v11.2.0
osmc@osmc:~$ nodejs -v
v8.14.0
osmc@osmc:~$

Downgraded with the help of this thread: https://stackoverflow.com/questions/7718313/how-to-change-to-an-older-version-of-node-js
Now it works again
