It is mandatory that deCONZ is connected to the network. So please check the gateway settings page in the phoscon app if it says “not connected” next to “firmware”.

Hi, thxs for answer.

On Settings page I see  
Vendor: dresden elektronik  
Product: ConBee II  
Version: 2.11.05 / 9.5.2021  
Firmware: 266B700

I made downgrade to this FW-Version manually, because some weeks ago, everything was working in phoscon app. I don’t know exactly when the error was the first time on which fw-version.  
I also have tested the latest beta versions.

Additional the conbee II stick is connected to a iobroker linux installation. With iobroker the control of the lights is working well!

Solved by changed the network settings to:

APS USE Ext PAN ID to 0x0000000000000000  
and TC Address to 0x00212effff06546b (the same as MAC address)  
and TC Link Key to 0x5a6967426565416c6c69616e63653039
