Hi, I am using Openstack Wallaby release with OVN on Ubuntu 20.04. My environment consists of 2 compute nodes and 1 controller node. ovs-vswitchd (Open vSwitch) 2.15.0 Ubuntu Kernel Version: 5.4.0-88-generic compute node1 172.16.30.1 compute node2 172.16.30.3 controller/Network node IP 172.16.30.46 I want to configure the ovn southbound and northbound database to listen on SSL connection. Set a certificate, private key, and CA certificate on both compute nodes and controller nodes in /etc/neutron/plugins/ml2/ml2_conf.ini and using string ssl:IP:Port to connect the southbound/northbound database but I am unable to establish connection on SSL. It's not connecting to ovsdb-server on 6641/6642. Error in the neutron logs is like below: 2021-10-12 17:15:27.728 50561 WARNING neutron.quota.resource_registry [req-94a8acc2-e0ca-4431-8bed-f26864e7740a - - - - -] security_group_rule is already registered 2021-10-12 17:15:27.754 50561 WARNING keystonemiddleware.auth_token [req-94a8acc2-e0ca-4431-8bed-f26864e7740a - - - - -] AuthToken middleware is set with keystone_authtoken.service_token_roles_required set to False.
