You might want to check the following:

1. if kuryr-libnetwork process is healthy and listens to port 23750 (do
this in each compute node):

   $ sudo systemctl status kuryr-libnetwork
   $ sudo journalctl -u kuryr-libnetwork > kuryr.log

2. if there is anything blocking the port 23750

  $ curl -X POST http://127.0.0.1:23750/NetworkDriver.GetCapabilities

If above doesn't help, you could paste me your kuryr-libnetwork's log (sudo
journalctl -u kuryr-libnetwork > kuryr.log) and config file
(/etc/kuryr/kuryr.conf).

This looks like a bug. I created a ticket for this:
