Conbee 2 configuration issue, multiple ips?

Configuration Zigbee
1

Dear all,

I have just started the whole Home Assistant journey. I am comfortable with the scripting, but hardware… I need plug-and-play! I started by making a backup of HA, so I could revert. My first attempted failed, so I reverted, and started over, multiple reboots, but still nothing.

So I have a raspberry with Home Assistant OS 6.6, everything is working well, but now, zigbee.

  1. plugged in the Conbee 2 stick with USB extension cord.
  2. hardware detection is OK:
ttyACM0
/dev/serial/by-id/usb-dresden_ .... etc
  1. Installed add-on changed config, to the above-mentioned. And start add-on
In log file of add-in

This just keeps on going.

  1. Open phoscon. On the right top I find an IP ending on 33.2.
  2. However when in phoscon I go to help > API information: it displays a cofig of /lcoal ip:8123/api/hassio_ingress/xxxx/api/xx/
"config": {
        "apiversion": "2.12.06",
        "devicename": "ConBee II",
        "dhcp": true,
        "gateway": "172.30.33.1",

I cannot add any products. Is this my problem?

Kind regards Ingrid
