Ubuntu version: Ubuntu 20.04.2 LTS (GNU/Linux 5.4.0-67-generic x86_64)
OpenStack version: Openstack Ussuri
Charm version: #5
After fresh openstack deployment (with vault and automatically generate a self-signed root CA) I get the following recurring errors in ovn-central logs:

I could not see any problems in Openstack / neutron-api. Everything seems to be working normally.
The ports in the errors always seem to change. This errors came up in all 3 ovn-central units.
I'm seeing this as well when deploying a focal-xena OVN bundle [1] on s390x. The system is working well, i.e. it's possible to create instances, give them a floating IP and SSH to them. But the nb and sb logs are full of these exact same SSL warnings.
