You have been subscribed to a public bug:

When neutron lbaas agent is not running, all the ‘neutron lb*’ commands
display "404 Not Found". This makes the user think that something is
wrong with the lbaas agent (when it is not even running!).

Instead, when neutron lbaas agent is not running, an error like “Neutron
Load Balancer Agent not running” must be displayed so the user knows
that the lbaas agent must be started first.

The ‘ps’ command below shows that the neutron lbaas agent is not
running.

$ ps aux | grep lb
$
