[ovirt-users] Hosted engine deployment fails consistently when trying to download files.

Hello, I'm trying to deploy a hosted engine on one of my test setups. No matter how I tried to deploy the hosted engine, either via command line or via "Hosted Engine" deployment from the cockpit web console, I always fails with the same error message. [1] Manually trying to download RPMs via dnf from the host, work just fine. Firewall log files are clean. Any idea what's going on?
