[ovirt-users] Re: not able to upload disks, iso - Connection to ovirt-imageio service has failed. Ensure that ovirt-engine certificate is registered as a valid CA in the browser.
I fixed it with below solutions
# cp -p /etc/ovirt-imageio/conf.d/50-engine.conf /etc/ovirt-imageio/conf.d/99-local.conf
# systemctl restart ovirt-imageio.service
