You should really start a new topic for that device issue as the root cause of your problem will probably not be specific to the Home Assistant SkyConnect dongle and regardless of any attempt at help with troubleshooting a specific device issue, it will get lost in a generic thread about the Home Assistant SkyConnect dongle as this is.
The only general advice can offer here is to recommend that you follow these two best practice guides:
Suggest that you instead first start by trying to follow all general best practices to optimize your setup, such as upgrading to the latest Zigbee Coordinator firmware, upgrading the firmware of all the devices that you have (including but not exclusively the devices that you are having problems with), upgrading the operating system and Zigbee software you that you using, making sure to use a long shielded USB extension cable to a USB 2.0 port (or via a powered USB 2.0 hub) and keeping the Zigbee Coordinator and problem devices away from USB 3.0 ports/cables/devices to avoid electromagnetic interference, changing Zigbee channel to one that does not overlap with your Wi-Fi, as well as adding more mains-powered Zigbee Router devices. Then lastly also re-pair the devices you have issues with at the location where they will be used.
Another general advice before troubleshooting further is to use “ZHA Toolkit” to do the OTA firmware upgrade of all your Philips Hue devices → https://github.com/mdeweerd/zha-toolkit
(The only reason why suggest using “ZHA Toolkit” to do OTA firmware upgrade of Philips Hue devices is that ZHA does not include OTA updates for Philips Hue devices by default, see https://www.home-assistant.io/integrations/zha#ota-firmware-updates ).
If still have issues then open a dedicated new topic thread for you device and setup, and there post device signature and diagnostic information + debug logs so people have deeper details to look at.
