Getting a 401 status error whilst establishing a connection to Concourse API - concourse

Question

At the moment, we are trying to get CI working in our labs..
we have just followed the instructions on the concourse website.
We are able to login properly and have setup ~/.flyrc as recomended ion the concourse-ci.org and concoursetutorial.com websites.
We have noticed that most commands are returning with a 401 Unauthorized error.
We have gone ahead setup the audit logs https://concourse-ci.org/concourse-web.html#audit-logs
But it isn't clear where this writes to, help?
It is difficult at the moment to properly trace this. BTW this is our first exposure to concourse.
We would like to know why? and what we can do resolve this (to cross this huddle).
