Delays on zigbee2mqtt?

I’ve noticed lately that my devices seemed to be delayed using Google Home (I have it hooked up to Nabu Casa). Sometimes Google will say it can’t reach Nabu Casa, or sometimes it’ll say ok, but the action are delayed.

My Home assistant is running hass.io with the zigbee2mqtt addon and Mosquitto broker addon. (I have the coordinator connected to a usb extension cable, and 50% of the devices on the network are acting as routers).
I had thought maybe it was my cc2531 coordinator so I upgraded to the Sonoff Zigbee 3.0 USB Dongle Plus but it seems to be the same.

Has anyone else experienced something similar lately?
