I have a licenced installation of Zulu. It is running and clients connect okay. However the Dashboard has a little “flame” icon next to Zulu and the caption “Zulu node is not running” when hovering over it.
I have done an fwconsole chown but this makes no difference.
We had the same problem, with a new install. Zulu node does not start until you manually start it.
Once started, it will remain running (even after reboots).
