I've tested on two different servers.
The one I am working on here, which is the one I sent the identification log for, has been running v2.23. I just updated it to v2.27, which I've also tried on the other server.
If I run https://iloip/xmldata?item=all I get a certificate error due to the self-signed certificate not being trusted, but if I click OK the data comes up. If I try using http I get the results just fine. Testing from the browser on the SIM server, BTW.
Thanks for responding Andrew.
