I made some progress. I realized I had turned on the Homebridge docker instance on the Synology NAS and when I stopped it, I got the docker webui to load on the homebridge instance on Unraid. I got into it and saw a plugin was out of date which was the config-ui-x and I told it to update but it never came back. I could no longer get the webui to load. I destroyed the container and image and deleted the /mnt/user/homebridge folder and installed a new container using host networking but made no other changes. I cannot get the web interface to come up at all. What am I missing? Is there some other configuration I need to add to the container to get it to come up when it's first created?
Here is what the log shows now:
