Unable up bootstrap Juju controller onto an Openstack cloud

We have an Openstack cloud (deployed and managed with Juju) and we want to allow users utilize it as a cloud provider for their juju deployments. The problem we have is that when juju runs from an instance inside the cloud it cannot spawn new instances. For example, If I bootstrap a juju controller from my workstation at home, it gets ready without problem. The exact same command from an instance that runs inside Openstack fails with the following error

The problem seems quite similar to this bug but no resolution available.

Any help is greatly appreciated!

Just to confirm, is this verbatim or are you replacing the actual IP address with this string?

I replace NOVA_CLOUD_CONTROLLER_PUBLIC_IP with the VIP of the nova-cloud-controller

FYI the problem is solved. It proved to be a misalignment in the MTU settings among physical hosts and switches. After aligning all of them, everything works as expected.
