(Resending it without the attached picture) Hi, It seems more a Neutron exception, and my 1st thought is to check your subnet and add it to your router, you can do it manually with openstack CLI: openstack router add subnet <router name/id> 98a65c6e-2473-48f1-a578-702a08649c73 Not sure if it is possible if you use trove as I never used it.
