Hi, This is explained in the https://github.com/oVirt/ovirt-engine/blob/master/DEVELOPMENT.adoc file under Connecting via console to your VM instance. what you are encountering is solved by doing the following: Upon encountering the error message "Something went wrong, connection is closed," please note that this is expected behavior. To proceed, you must accept the SSL certificate in your browser. Access your browser's development console, copy the `wss://XXXXX` URL, and paste it into your browser's URL bar. Replace `wss` with `https` and navigate to the URL. Here, you can accept the certificate. You can reopen the console via the oVirt administrator panel.
