Just confirmed that a reboot does not resolve the issue. It appears V. 5.6.9.3 behaves like V. 5.9.6.1. and V. 5.9.6.2 resolved it. I can actually get things to work with v. 5.9.6.3 but I have to play around with stopping and starting the services. I basically stop Codeproject service first, then attempt to close
Blue Iris but it times out before actually stopping. Once it times out, I manually restart it again and Blue iris starts Codeproject service automatically because that's how I have it set up to do. Once this process completes, I can see the ipcam-combined again in custom-models and it starts to actually detect properly. If i reboot though, everything stops again until I manually do the service thing again. Quite buggy it seems. I will probably try downgrading to V. 5.9.6.2 again.
