Migrating from Sonoff to SLZB-06 - can't add new devices

Configuration Zigbee
1

Hi everyone,

For the last few days I’m trying to troubleshoot why I cannot add new devices after migrating to SLZB-06.
I’m able to control the existing devices.
The SLZB-06 is connected directly to my router via LAN cable.

I unplugged the Sonoff zigbee coordinator from my HA server.

This is my current Z2M config:

data_path: /config/zigbee2mqtt
socat:
  enabled: false
  master: pty,raw,echo=0,link=/tmp/ttyZ2M,mode=777
  slave: tcp-listen:8485,keepalive,nodelay,reuseaddr,keepidle=1,keepintvl=1,keepcnt=5
  options: "-d -d"
  log: false
mqtt:
  server: mqtt://homeassistant.local:1883
  base_topic: zigbee2mqtt
