No video

The console and the video take different routes, so the console can work while video does not.

Check in this order

Is the relay running? On the device:
Terminal window
```
docker ps --filter name=edge-relay
```
If nothing is listed, start it with docker start edge-relay. A relay that was stopped by hand stays stopped on purpose. Within about 30 seconds of it returning, the backend puts the camera paths back without a restart.
Is 8189/udp open? If the console connects and reports a connection but no video ever arrives, this is the usual cause. Allow 8189/udp between the browser and the device, along with 8889/tcp, 8554/tcp and 5080/tcp.
Is the camera reachable? Open Cameras and test the camera. The camera state names its cause. A camera that is off, unreachable or rejecting its login shows no video however the device is working.
Did an update leave the relay down? The last line of an update that says but the relay is NOT running means the device runs the new version without video. Do not install again. Send ~/edgevision/install.log to support.
