I'm testing OCP 4.3 2019-11-19 nightly on OSP 13.
I added my CA cert  to install-config.yaml  and the installer now progresses. I can even `oc get nodes` and see the masters. .
I still have the following errors and no worker nodes though.
This is likely a symptom of not yet having associated a floating IP to the app neutron port, and not having created an /etc/hosts entry on the installer host. I assume that's a nonfatal error.
I assume this one is fatal, however:
$ export KUBECONFIG=osp-nightly/auth/kubeconfig
$ oc get nodes
