Openhab Cloud doesn't work

[EnziinSystem]

The project seems to have been abandoned and it is no longer active at this point.

The application start command exits silently without any error messages.

$ sudo node app.js
$

With a config file:

    "system": {
      "host": "domain.com",
      "port": "443",

No, the project is active, but work tends to happen only when needed. Its primary purpose is running our free myopenhab.org service for openHAB users. I'm not sure why you are not seeing any error messages, you might try our community forums for help as there are users there that run this themselves.
