Hue-emulator.service failed after reboot

I’m not sure what the mqtt implementation means or what the library issue is or was?

Since moving to a docker installation, I can no longer connect to the diyHue bridge with the official Hue app because it doesn’t register clicking the “Activate” button. In Hue Essentials it does. Does this have anything to do with that? Other than that (and a Timezone problem) I haven’t noticed a difference so far.
