Philips Hue Outdoor lightning strip

What is going wrong ? I installed the strip with Zigbee driver and everything was ok. Used it in flows etc. no problems. After two weeks the strip did not work anymore. I tried to reinstall the strip (unpaired the old one ) but not possible to pair. I removbed the Zigbee driver and installed the same again : no result.
“time to install to long” or “status.already_running_command”.
What does this mean ?

Anybody suggestions ?
