ZWaveJS2MQTT isn't opening websocket for HA - why?

I’m running Bullseye on a Pi 4.

I’m attempting to get Home Assistant to communicate with ZWave2MQTT - I can reach both via my web browser. I have ZWave2MQTT set to enable the WS Server on port 3000. HA doesn’t see it. My chrome ws debugging tool doesn’t see it. I don’t see anything in the logs - just to verify, where would I likely see anything in the logs?

UPDATE - netstat doesn’t see the port open either, although it does see the web app port which I’m able to connect to

I got it working. It was necessary to remove the serial port from the HA zwave config. Then ZWaveJS2MQTT could see it and the web socket port was created.
