# No video

> The console loads but a camera tile shows no picture.

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

## Check in this order

1. **Is the relay running?** On the device:

   ```bash
   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.

2. **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`.

3. **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.

4. **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.
