The ovirt-provider-ovn fails during checking the credentials at
engine's sso because of a networking problem.
That would be odd - after all we're using the loopback interface
From: ::ffff:127.0.0.1:49582 Request: GET /v2.0/ports
but please try the url.
Can you please check if the url of the config value
ovirt-host in
/etc/ovirt-provider-ovn/conf.d/10-setup-ovirt-provider-ovn.conf
can be reached from engine's host?
If this does not explain the problem, can you please increase the
logging of the ovirt-provider-ovn by
sudo sed -i.$(date +%F-%H-%M) 's/INFO/DEBUG/gi'
/etc/ovirt-provider-ovn/logger.conf
systemctl restart ovirt-provider-ovn
and share a new detailed error in ovirt-provider-ovn.log?
Thanks.
Dominik, could it possibly be related to our hardening TLS ciphers?
If it is, setting (an insecure) ssl-ciphers-string=DEFAULT in
/etc/ovirt-provider-ovn/conf.d/10-setup-ovirt-provider-ovn.conf would
help.
