Docker/DECONZ: Will not connect to any devices after restart

I am running zigbee2mqtt (1.16.1) as a docker service on a Ubuntu server. The DECONZ stick is plugged into the server via a USB extension cable.

A couple of the paired devices lost their connect to the system. So, I tried restarting the docker service. Now nothing is communicating! I have not tried repairing everything, but this is not the correct solution.

Help! What next?
