Hi, I have image upload/download working on some older ovirt servers where it still has the split daemon/proxy... on one newer one this feature is not working; software in use: CentOS 8 ovirt-engine-4.4.1.10-1.el8.noarch ovirt-imageio-client-2.0.9-1.el8.x86_64 ovirt-imageio-daemon-2.0.9-1.el8.x86_64 ovirt-imageio-common-2.0.9-1.el8.x86_64 the ui test button allowed me to work out 50-vdsm.conf was setting the wrong remote port... (was 54322, changed to 54323) updated remote with; [remote] host = 0.0.0.0 port = 54323 the test now passes, but on upload or download it still fails. Next i changed the control to be unix socket instead of tcp port 54324 (vdsm was giving an error: Image daemon is unsupported); I looked up the error line in the vdsm code, and found it was looking for unix socket: DAEMON_SOCK=/run/ovirt-imageio/sock switching to sock seemed to resolve all errors in the vdsm log; --- content of the imageio log; no errors as far as i can see: 2020-08-18

button passed after changing remote port to 54323... any help much appreciated.
