Just so we end on a informative note for this one and Nick absolutely thank you for your help here. The solution to clear the swift stack nodes errors was to reboot the proxy nodes sequentially and then the 401 error along with the other message went away.
Also if you are wondering you can either manually issue a "sudo reboot" on the swift stack proxy nodes or you can go into the Controller GUI ---- > Clusters ----- > Manage ----- > Restart Proxy Services On Swift Nodes.
Hopefully this will at least help someone else.
