UPDATE:
Okay so after editing the conf files. and running the above commands
I still see the old network key show in the PS log but the actualt log files for the staller docker imagine have the following:

so It seems I have either caused more issues and haven't hit the network keys not matched error or I'm passed that and hitting a corrupt with the buckets. Though I don't know what that would be or how to fix it. I can also delete the mounted directory contents and go back to square one if needed. Though I have done that many time now as well.
