network fail to start in controller node

After the installation of the controller node on ubuntu-server 18.04 and the configuration of their environment. After the creation of virtual networks, networking are failed to update or get something from internet but the command "service networking status" return active status and the "ifconfig" return a lot of network cards

Everything works on my controller node besides the launch of instance it return always an error status using the command "openstack server list" I tried to launch the instance manually and from dashboard and i failed in the two cases

How can i fix these errors ?
