ZHA Zigbee bulbs not responding

So I have some Zigbee bulbs and lately i have noticed that they seem to not respond, unless i restart HA. I just updated to 91.3, and I’m running Hass.io on a RPi 3, using the HUBSZ-1 stick.

Anyone have any ideas why this is happening? My Z-wave switches are responding and work fine.

thanks.
