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.
I had similar problems for a long time and finally ditched the Coral. I even made a post about it, and you may find it helpful https://wetshav.ing/post/93365
Also Proxmox does not recommend running Docker in LXC and instead they recommend a VM.
Edit: actually you commented on that post of mine, so that’s funny!
My server is also running an Intel chip so maybe I’ll play around with using that instead. How is your performance? I have six cameras running but frigate only sees the lower bitrate streams as I have a standalone NVR in the mix already. All I use it for is object detection so that I can get notifications when someone approaches the house via Home Assistant.
I decided to try the LXC route as I also have Immich running in a separate LXC and wanted to share the Coral with both and AFAIK you can’t share resources between multiple VMs (though I’m pretty green with Proxmox/Linux based systems)

“Rock solid” may have been a bit premature 🤣
I just read that Google has abandoned the Coral TPU.
I expect OP’s issue came after a recent kernel upgrade
Sounds like everything is containerized; I would start rebuilding the container.
I restored from a backup from months ago when I’m sure it was still working and didnt have any luck, but thinking about it now this may have been before I had solved the issue with the Coral not being found. I’ll try that again tonight when I get back to the server.
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.
