Could you show your bridges on the host too? And your openstack_user_config.yml?
When the repo-server gets installed, it installs a reverse proxy. All
the nodes are then configured to use the repo server(s).
So all the nodes need to reach it, on the management network.

Here you are a little early in the steps, you can't install the repo
server because you don't have connectivity in your containers. That
shouldn't happen. You have maybe a misconfiguration, or something
happened to your containers that ended up with no IP assigned on the
Maybe try to restart your repo container, see if it works better. Else
I'd advise to debug this problem a little more in depth.

You could join us on our irc channel #openstack-ansible for help.
