BTW, I figured this out.
The problem is that the docker compose on Docker mentioned VISION-SCENE, but not VISION-DETECTION. My assumption is that this was a changed environment variable, but it's not. Setting VISION-DETECTION was the culrpit.
I am awkwardly stuck on setting up Deepstack integration. Here's what I have done.
Blue Iris Server - 192.168.23.25
Deepstack - 192.168.23.26:83 (within Ubuntu, using Portainer)
1. I'm using Portainer to hold the Deepstack container. I can confirm that I can get to Deepstack landing page...
