I currently have frigate running on my Proxmox server in an LXC running Portainer and it has recently quit detecting anything and sending out notifications when someone walks up to my house.

I sat down to do some troubleshooting last night and first discovered in the logs that it wasn't detecting my Coral TPU any longer but after reseating the USB cable and rebooting the container that issue is gone. Now everything 'appears' to be working properly but it still won't detect anything and I'm at a loss on how to proceed.

Checking the logs, no errors are displayed. I can see all my camera feeds on the main view. The config hasn't changed. My masks are still in place. I dont recall the exact names, but the Settings>'Status' (with the bar graphs) window shows the Coral TPU as connected and used and Settings>Debug windows shows red boxes around moving objects, but I don't see any detection events, no short clips, or any other indicator that it's working.

Edit: well this is stupid but it was a frigate update that caused the issue. With 16.0, you have to add "enabled: true" under "detect" for each camera to get object detection. I hadn't updated it for some time and didn't read the release notes.

Restart the docker service or whole server.

I tried different levels of reboots from frigate to portainer to the LXC and finally the host running Proxmox as part of the troubleshooting with the Coral then again once I got it connected and still didn't have any luck.
