Hue play gradient lightstrip wont connect after bridge update

My hue play gradient lightstrip stopped working on the same day when the hue bridge got an update. The bridge listed it as unreachable. I have checked everything: power supply, entering the serial number, resetting the lightstrip with (2 sec on, 8 sec off) x 5. The bridge doesn’t find it. Can you help me?

Bridge software: 1.65.1965053020
