Comment 2 for bug 1638908

I don't think this is specific to quickstart - I hit this locally yesterday on my instack-virt-setup/tripleo.sh environment.

AFAICS the error comes when trying to store the plan data in swift, because I saw it when attempting to upload a deploy artifacts tarball, not on overcloud deploy.

Unfortunately we don't seem to configure logging for swift on the undercloud and thus I couldn't find any clues as to why it was failing, further investigation needed but eventually I rebooted the undercloud which "fixed" the issue.
