Hi Ryan

...[XMLRPC-GROUPS-CONNECTOR]: Root element is missing...

This usually indicates that the response from jOpenSim to OpenSim was a "not well formed" xml format ... many times caused by some php notices or warnings.

Allthough I try my best to avoid them as much as possible, it never can be impossible.

What is your error_reporting setting? And if you enable group debugging in jOpenSim, is there something like "NOTICE" or "WARNING" in interface.log?

Hi foto50

I enabled debugging for groups and the message in interface.log is

2016-06-23 11:20:18 Request coming from 192.168.2.1

I think I can see the problem if not the solution

line 297 interface.php
if($opensim->checkRegionIP($remoteip) === TRUE)

The application is logging that 192.168.2.1 is making the request this is the internal ip address of the network router, joomla and opensim are sitting on the same server for testing so it thinks the request is coming from the LAN address of the router not the WAN address
however in the regions database the ip address stored for the region is the external public ip address 81.x.x.x

as these do not match the rest of the code is being ignored

This is indeed the cause for missing communication, since I try my best to keep jOpenSim as secure as possible.

I'm not sure if this helps in your case, but I had a similar case where I added in OpenSim.ini in the [Network] section:

Hope this helps to force the requests made with the WAN address.
