Zigbee2MQTT enters error state when Home Assistant is running

I am building a HA system on Raspberry Pi 5 using docker containers for all installed apps.
The following apps are installed:

  • Eclipse-Mosquitto
  • MQTTX
  • MQTT Explorer
  • Zigbee2MQTT (using SONOFF USB 3.0 Plus Dongle)
  • Node-Red
  • InfluxDBv2
  • Grafana
  • Code server
  • Home Assistant

All has been running well and without error. The final app, installed today is Home Assistant. Here is the docker compose file:

services:
  homeassistant:
    container_name: homeassistant
    image: "ghcr.io/home-assistant/home-assistant:stable"
    privileged: true
    network_mode: host
    restart: unless-stopped

    volumes:
      #- /PATH_TO_YOUR_CONFIG:/config
      - ../../volumes/hass/config:/config
      - /etc/localtime:/etc/localtime:ro
      - /run/dbus:/run/dbus:ro

When Home Assistant starts (enters onboarding - not yet started) Zigbee2MQTT fails to execute LQI. Here is the normal Zigbee2MQTT log:

[2025-06-15 13:56:25] info: 	z2m: Zigbee2MQTT started!
[2025-06-15 13:56:34] info: 	z2m: Starting network scan (includeRoutes 'false')
[2025-06-15 13:56:35] info: 	z2m: Network scan finished

Here is the log when Home Assistant is running:

[2025-06-15 13:55:44] info: 	z2m: Starting network scan (includeRoutes 'false')
[2025-06-15 13:55:51] error: 	z2m: Failed to execute LQI for 'Coordinator'
[2025-06-15 13:55:51] info: 	z2m: Network scan finished
[2025-06-15 13:55:51] info: 	z2m:mqtt: MQTT publish: topic 'zigbee2mq

Have removed HA container and rebuilt: same impact on Z2M.
Zigbee2MQTT works fine after stopping HA and restarting Z2M.
No other containers are affected. No other errors anywhere. Only Z2M seems affected.

Being completely new to HA, I’d appreciate some insights and the sort of investigative steps I need to take.
Thanks, Ric
