[ovirt-users] Cannot import a qcow2 image

Hello, I' m trying without success to import a qcow2 file into ovirt. I tried on a ISCSI datadomain and an nfs datadomain. I struggled quite a lot to have the "test connection" succed ( I write a small shell script to "deploy" letsencryt certificates into ovirt engine) Doc is not clear on the fact that certificates for imageio-proxy are different than for main engine… Now, the upload fails with Transfer was stopped by system. Reason: failed to add image ticket to ovirt-imageio-proxy. Image gets stuck in "transfer paused by system" Any idea ? ovrit is up to date: 4.2.4 on both engine and hosts.
