I recently made a post in the showcase section for the Shadow of House (Generate SVG) section. I received some helpful information, but I continue to receive a Java error that I assume would be better dealt with here than in the previous post. The error follows. I suspect that are some config settings that I need to adjust, but I don’t know where. This is the first error encountered.

I’ve been chasing my tail all night long with this. Reloaded numerous times. That address is part of the installation script I’m guessing, I didn’t do it. How can I change it?? Also, since it deals with DNS, I use PiHole on my network, could that be causing any problems??
You need to examine the log entries before the ERROR to try to determine which binding is causing the error. Then you can put the binding into DEBUG and get more information on what’s causing the problem…
