I brought this up on G+ but this should be documented.
I previously ran HG on Server 2008 without issue. When I upgraded, HG is locking up on Server 2016 and the background process is continuously using 10% CPU. Loading the web interface locks up and rarely completes. However, using the app to turn on and off devices works and the security alarm worked. My API string to turn on the security alarm rarely worked but using the string to turn it off did work most of the time. Not sure what’s wrong there. I have resolved the issue for my needs now that I’m moving my server to a VM on a Windows 10 machine so I can just run HG on the Win 10 machine but ultimately I would like it to be running on the server OS.
