Kapacitor 401 unautherized

Hi,

I'm trying to follow the getting started documentation. I followed the instructions and ran `./sandbox up`
the web site start up OK but then when navigating to the "Hosts Lists" I get an "Unable to get hosts error"

Looking at the containers I see sandbox_kapacitor_1 has stopped.
looking at the logs I see the following
