Hello everyone,
I have installed environment like described in example below:

Only configuration change that i have done is adding
CATALINA_OPTS="-Dsynchrony.proxy.enabled=true {CATALINA_OPTS}"
CATALINA_OPTS="-Dsynchrony.service.url=http://192.168.0.1:8091/synchrony/v1 {CATALINA_OPTS}"
to setenv.sh.
I have configured and started synchrony as explained in:
https://confluence.atlassian.com/doc/installing-confluence-data-center-203603.html
2. Setup Synchrony
in atlassian-confluence.log i have this info related to synchrony:

Synchrony Interop Bootstrap Plugin (com.atlassian.confluence.plugins.synchrony-interop, Version: 6.3.1, Installed: bundled)
In admin/confluence-collaborative-editor-plugin/configure.action site i have error:
We couldn't connect to your Synchrony cluster from this Confluence node
and synchrony URL
http://localhost:8091/synchrony/v1
Can someone point me in right direction how to fix this.
I assume that synchrony url should be http://192.168.0.1/synchrony/v1 but i don't know where to change this.
Thank you all.
