You should modify only instance config

In your instance conf, set autostart="true", and fill out the IP element, e.g.:

<IP address="" heloHost="localhost.localdomain" publicId="1" weight="1"/>

Then restart nlserver6 service.


NB You have a relay address set in your serverConf.xml. If intended it should be moved to the instance conf- serverConf is supposed to be used as a read-only reference.

Quick note- use for relay address, for whatever reason whenever I tried localhost it would fail.
