DL201 Service not running

503. The hostname belongs to a stopped service: its lane is stopped, or the service was stopped or left out of the last devlanes start. Routes of stopped lanes stay registered, so the page can name the lane.

devlanes start --lane acme@2      # the whole lane, as the page shows
devlanes start acme@2:web         # only this service
devlanes debug why acme@2:web

A box lane is started on the box; the connection only mirrors it.
