I 'm facing an issue starting Zigbee2MQTT on a Raspberry Pi 4, latest HAOS version. My Raspberry is placed very close to my router, I'd like to get rid of the Ethernet cable and use the Wifi connection (I know, not ideal, but I prefer to have a clean desktop). Everything is working fine with the Ethernet connection, I can ping my SLZB-06 hub from the HA Terminal console, Zigbee2MQTT is running ok. When I change my connection to Wifi, disabling the Ethernet setup, using same IP address, I can't ping anymore the Zigbee hub and Zigbee2MQTT is not starting.
