Chef Server 12.01 - Spontaneous Client ERROR: 403 "Forbidden"

I have recently upgraded from Chef Server 11 to 12 and have come across a
very frustrating issue.

I have a set of nodes that are converging fine and then poof they
spontaneously can not set their node state back up to the chef server at
the end of the run.

Can anyone point out some things I might do to troubleshoot this issue. I
am including what I think are helpful logs but I am sure there is more than
I can submit.

The only way that I can fix this is by deleting the node and client and
reestablish them.

Thanks!

Server = CentOS 6.6
